SPOILT FOR CHOICE
Hi Jim
I've owned Version 1 of each Cruzbike you mentioned, and newer Versions get better too as user feedback filters back: a virtuous circle. John Tolhurst continues to be the engine room for innovation, but he is keenly attuned to feedback from the Cruzbike community.
My (continuing) Cruzbike story is at:
http://www.cruzbiking.com.au/threetwoone (and an earlier version on the Silvio brag board).
Here's the rub. I've also taken up riding DF road bikes recently as part of a personal experiment (N=1) on exploring the differences between the styles of riding. The motivation for the experiment was to explore personal issues with recumbent hill climbing, and I'll start a thread on that later as the experiment progresses. On the flat, your legs and your heart are in the same plane. But going up a steep hill your legs will be higher than your heart - on any recumbent - not just Cruzbikes. Is this a problem - no idea? And this is in addition to the usual consideration of recumbents exercising different muscles - the need to develop "bent" legs - if that's really an issue.
The two common factors I've found in climbing hills on a DF and Cruzbike are:
1. It's hard work on both, and
2. A low gear and a high cadence is the best strategy on both - stay seated, and relax, as much as possible.
In DF Cyclocross and some mountain biking it's common to see riders leap off their bicycles and run / walk some of the time. Maybe I'll come to terms with walking up really steep hills, where it's not an option to get out of the saddle - as it is on a DF - to just increase the cadence before you sit down again and spin. Interestingly, Bradley Wiggins found he had to lower his cadence in the BORAF, slightly, to maximise his power output. Would that I had that problem.
I also wanted to write a sequel - "My Journey to the Vendetta" - but that's not going to happen for a while and I'm working through issues with riding a Vendetta with Kim Tolhurst. In a nutshell, starting off and low speed manoeuvring is difficult for me on the Vendetta, because of the extreme recline. Once riding, it is almost effortless, and an astonishing experience, so I will persist.
Like most of the population, I never flew on the Concorde, but I like to think there is a similarity with the Concorde drooping its nose for takeoff and landing, and then retracting it for supersonic flight, see:

But I digress.
At the moment Jim, my Cruzbike ride is my Quest 451 V2. My Silvio V1 is in bits as I ponder converting it to a Silvio V1.5, or selling the frame (offers?) and saving up for a Silvio 1.5 frame. The Sofrider was sold a long time ago.
I think Charles is on the money suggesting the Quest 451 V2 for portability and its technological (Q-ring, SRAM Dual Drive Hub) aspects. And Randy is right to ask what sort of riding you plan to do. BTW, I had no trouble getting Schwalbe Durano 28-451 tyres for my Quest.
I think the Quest 451 V2 is the easiest Cruzbike to start the Cruzbike experience with. I recently did a relaxing 42 km ride with Kim Tolhurst that had a several rolling "inclines" of 3-4 per cent and a couple of steeper 6-8 % "pinches". Just for reference, a 1.3 km climb at an average grade of 6.4 % is rated as a Category 4 climb (the easiest) for road bike races. I'll let you know how I progress through the Categories - if I get that serious.
One emphatic recommendation is that you watch Kim's riding instructions, see:
http://www.cruzbiking.com.au/firstride I'm fortunate to be on the same continent as John, and close enough to Kim to go riding together. However, I bought my Sofrider, sight unseen, but I only really got it set up when I met Kim. We're trying to make that experience available in the videos.
WRT to your DF riding, I can thoroughly recommend "Just Ride", by Grant Petersen, see:
http://www.amazon.com/Just-Ride-Radically-Practical-Riding/dp/0761155589 - and Cruzbikers could enjoy it too. And Petersen explains (if you haven't guessed already) what BORAF means, and why its influence is not always good.
On the DFs, I still find I'm getting sore wrists to some extent, but back, neck and saddle "pain" have been largely eliminated on 80km rides by getting fitted by Andy Choy at BikePro. He's not into the snake oil that seems to be peddled about, and as you get fitter he'll make minor adjustments. His treatment, if you live in Australia, and can visit him, is described at:
http://www.bikepro.com.au/bikepro-fit- but if you are overseas, then there's a DIY page at:
http://www.bikepro.com.au/diy-bike-fitting
Andy helped fit me to my Silvio, put me on a PowerTap and showed me how pedaling technique could increase my power output. It did. Andy is a fan of Cruzbikes and the design philosophy of the Silvio in particular.
I took my first DF, a CELL Victor (carbon) to Andy to be fitted, and then bought a Lynskey Sportive (titanium) from him. Both weighed in at around 8kg. I'm sure if it could be done at a reasonable price, John would trim weight off the Silvio, with maybe a carbon or titanium version, but this is a big ask for a small market. And while the Quest and Silvio are both heavier, they are not heavy bikes. It's easier to trim a few kilos off your own frame than to shave grams off a bike.
The Quest wasn't available when I started my Cruzbike journey, and neither was the Sofrider V2. The Silvio V1 was a fantasic experience. My first long ride on a Silvio, with virtually no preparation, was 70km. No pain anywhere when I finished either.
So, in many ways I envy you and the choices and experiences ahead.Cruzbikes (or recumbents in general) may not be for you, but while my experience of RWD recumbents and trikes is limited, the Cruzbike FWD design philosophy just makes sense.
At the moment, I'm in a Greg LeMond headspace - "It never gets easier, you just go faster." - and I've made a detour to DF road bikes, while I ponder the Vendetta. It's interesting to read other Vendetta posts where Paul (fthills) said he had to forgot all his previous riding experience and start from scratch with the Vendetta. That's what puzzled me. I was an experienced Sofrider, Quest and Silvio rider, and yet the Vendetta threw me (not literally).
Knowing what I know now, and had it been available, I think I would have chosen the Quest 451 to start the journey.
Good luck and welcome.
