Howdy krotch,
First post on this board ...please indulge.
I don't know whether to try and give you my lame opinion or just imagine how fun it is to be you on your quest to decide between three awesome rigs.
I currently ride Titus' RacerX100. My choice was ultimately an economically motivated one. A hookup is gold. I got that rig 18 months ago. I had been going back and forth between the Intense Spider and the Titus RacerX100. The Titus was the favorite in the running. It was the wait for production to catch up with demand that made life difficult for me.
Your choices are very compatible except with the notable exception of the rear suspension design. I preferred the Titus because of the FSR rear linkage. I believe that the Horst Link suspension design is the way to go. VPP is very cool, but I think it takes a back seat to FSR.
Also, the Titus is going to have a slightly shorter chain stay than the your other options. So, it's going to be a 'bit more tenacious as a climber.
Another motivater for my Titus desire was that I had heard from a reputable source that Chris Cocalis got some input from Chris Chance on the geo of the Racer X rear triangle.
I rode a Fat Chance Yo Eddy for 8 years. I loved that rig. I was all juicy about getting a FS frame that would behave like that Yo Eddy.
Above all, I believe that the rig is just meat and you, my friend, are the motion. Have fun with your decision. You're a lucky dood to have this problem.
