That looks interesting MacG. I don't mind the weight as I am always riding on flat ground and most of the time I have only 1 traffic signal to deal with.
My Very First Recumbent is a V20

That looks nice and fast Jeffers. I've been through several bags already and my similar 1 to yours is the 1 I like the most.

Rookie mistake?
Schwalbe has so many tires in the "ONE" series. "One" (tube type), "Pro One Addix" (tube type), "One (tubeless), "One Performance Addict" (tube type), "Pro One (tubeless), "Pro One TT TLE Addix" (tubeless), "Pro One TLE Addix (tubeless), "One TLE Performance Addix" (tubeless) "One V-Guard" (tube type), and more. I may have made a mistake there, but there are so many that I am not going to go back to double check.
What I have had on my V20 for a while is the Schwalbe ONE TLE Performance Addix which by name sounds like a decently fast tire, especially because it is tubeless, but in actuality has higher rolling resistance than Conti Ultra Sport II (tubed) and Grand Prix 4-Season (tubed). It is barely faster than a Durano. Compared with with Conti GP 5000 TL it has 8 watts per tire higher rolling resistance. That is almost double the rolling resistance. No wonder I have been feeling sluggish lately.
Gonna buy the 700x30mm Conti GP 5000 TL with the brown sidewalls tomorrow.

I use a Schwalbe one in 451 on the front of my low racer, and a Conti 5000 on the rear.
20" 451 is kind of limited but I'd like a Conti 5000 on the front too if they made them.
Only thing I don't like about the 5000 besides price is they're very prone to slicing type damage.
More prone to that kind of damage than the Conti Ultra Sport. Must be the rubber compound.
'Brown sidewalls' great idea where people walk their dogs!

They look great by themselves. Not sure how they will look on the bike but luckily I don't spend a lot of time staring at the bike when outside.

Instead of the tubeless 700x30mm Conti GP 5000 I went with a pair of 700x28 tubed GP 5000 with the brown sidewalls because I didn't think the 30mm would fit because the Schwalbe 28mm I have on the back now just barely clears the brake bridge. However, the Contis are much more narrow than the Schwalbes despite the claimed width being the same.

I chose the 25mm over the 28's based on their ability to take higher pressure than the other sizes.
Most of my route is on smooth surface and I've got a large oil type compressor in the garage.

The 25mm tires are great for smooth roads. My path is quite smooth so they'd be excellent tires for it. If my LBS had them in TR in stock on Saturday then I would have chose those over the tubed 28mm just for that reason. Now that it seems that Contis run more narrow than Schwalbe, and how much room there is leftover then I am definitely going to buy those 30mm TR tires if they are still in stock when I return. I did put sealant in the tubes though so at least I still get a bit of protection on small punctures. Gonna give them a try today but part of the ride might be with a friend on a DF.
Are there any wheels you guys are using that are wide enough to match the 28-30mm tyres in terms of aero? I find most wheels are aero optimised for 25mm these days. I've never tried 28-30s myself, but I imagine ride comfort of 28 would be similar to 25mm at the same pressure.... but of course you can run less pressure on 28s. I'm running about 70psi on my 25s these days. Seems pretty comfy compared to >100psi previously.

Adrian, my 50mm and 80mm deep Bullets are C15s and Sciroccos (C17s) are likely matched with 23mm and 25mm tires respectively for better aerodynamics. 28mm GP5000 on the Sciroccos probably wouldn't cause a huge loss at the brake tracks since the rims are 2mm wider than the Bullets, but they are only 35mm deep. Now they are on my DF bike, but Monokoting the Sciroccos and running either 28mm or 30mm TR tires on them would I think make a it a relatively inexpensive, fast and comfortable wheelset for all but the worst roads. If I ever take my V20 out of Japan for an event then I might even go up to 32mm on them (if they fit) if the road conditions are rough. If I were riding in a velodrome or on a dedicated track with an excellent surface then 25mm is probably the widest I'd go with just to get the frontal area reduced as much as possible. I saw some 19mm tires at an LBS but I ain't gonna try those lol.
I ran 18's back in the day. Thought they were super fast now I run the biggest tire I can fit. Priorities change.

Finally got the SRAM AXS Wireless Blips in and installed them on my Deda Tribar with Campagnolo Super Record TT brakes. Can't wait to try it out.

After adjusting the bar angle a little higher the bars felt okay. At first I had the Blips on the top and while the supplied 3M double sided tape holds them on the bars well, it doesn't take much pressure on the side of the buttons for them to be pulled off. So, I went to the DIY shop to buy some foam handles. I installed them with the buttons on the inside of the bar instead of the top, covering the bottom half of the buttons with the foam handles. Some advice from 1 of the gurus here suggested trying to cover the whole button, so I'll try that. Hopefully the foam over the top won't hold the button down.

I really love the look of them especially when they are horizontal. That position is tough on the wrists, but looks awesome. On the bike stand for the test ride I put them in the lowest position I felt I could tolerate, expecting to have to raise them at some point. Since my hand position is different than the drop bars, I needed to use different muscles for steering input so the 5km ride through traffic to get to the river was not the smoothest. Once I got to the river I flipped them up a bit more and got used to them as the miles rolled in. During the ride though, and hoping to keep them as low and aero as possible, I didn't feel I could pull on them for power as well as I could with the drop bars I had on. It's only a few watts and a few grams of weight, but if I were to try to make an argument for them over drop bars then I'd have to argue that they are good for the long distance at a lower and steady power rather than using as levers for pulling. Maybe lower and a bit more forward would help in using them to pull, but my boom is straight.

Hoping for better CdA, but I don't think they are going to help much if any. I had them on my DF bike and they were just sitting around so I thought I'd give them a try with the wireless Blips. The weight savings over the brifters on aluminum bars is probably decent, but that really doesn't matter since my Strava elevation data is as flat as Elvis' heart rate monitor.
Other than tinkering, I hope someone can learn from what I do with my V20 to see if they want to do the same, or rule it out as being not worth the effort or cost, or offer suggestions such as Jeffers thumb grips for a final touch. Now that I know those are a thing then I have another possible solution.
