I've had the Silvio 2.0, S40 and Vendetta. For me, the Vendetta was the most comfortable, with the Silvio coming in second. As for speed, the Vendetta, but the other two weren't slouches either...
I like the wider tire options on the S40 for Texas roads, but couldn't get really comfortable with the 40 degree seating... I got recumbutt, so sold the S40. I've seen a couple local folks Bikepack on a Vendetta, but as Robert said, the S40 is built more for that...

Well, this is a nice disccussion.
@cruzKurt , glad you finally got a V20!
I've never ridden a V20 but Iam blessed to have a S40 gifted to me by some great friends here. I love my S40 and I ride it alot despite my initial fit and hotfoot issues.
I can personally confirm that the S40 with the stock seat indeed has a recumbutt issue (probably not affecting everyone). But I believe it can be fixed or reduced. I think it is cuased by the shape and design of the stock seat when in combination with the 40deg recline angle.
(Probably I should have started a entirely different
thread (here) all together about
how to fix recumbutt on S40).
First and foremost, the boom should be properly adjusted to allow optimum knee bend(145-155deg) while at a full leg extension of the pedal stroke. (
Bonus tip: If you experience numb feet(aka hot foot), set the cleats about 25mm
behind the ball of your feet. I personally just drilled my old spd shoes and moved the cleats backwards. No need to spend money on custom shoes. Then adjust the boom to compensate for the change in the effective leg length.)
The stock seat has an adjustable plate at the bottom that should be extended out to give proper support and hence avoid the likelihood to slide forward on the seat.
The shape of the bottom of the stock seat also lacks the necessary bowl-like curvature and therefore cuases the glutes to seat realtively flat on the seat. Consequently they bear the forward sliding weight while pedaling.
The key is to find a way to slightly suspend the glutes. I used some pieces of form padding on the edges to create a bowl like shape which reduces pressure on the glutes. I hope this makes sense.
All in all, proper shoulder/neck support (note my plastic diy neck rest), relaxed hands, a little patience plus these modifications may reduce or resolve the recumbutt issue on S40. However, you may need to give it a few rides and allow your body to adapt before you make your conclusions. (Oh yeah, and I reduced the thickness of the stock pad slightly .. -20mm or so. It was too thick for my taste.)
Cruzbike recently released an adjustable carbon seat for the S30/S40/V20/V20c which I guess probably
@Robert Holler and team took into consideration these matters. I have not tried their new seat but hope it is way better and wider than the stock seat.
