I had a chance to ride mine today, and I'm very pleased. The fit of the 61cm RS is much better than my 58cm Flyte, which was my main reason for buying it.
The first thing I noticed was how stable it seems compared to my Flyte. I'm using a 100mm stem with 42 cm bars because of my short torso, which made my Flyte feel a bit quick in the steering department, but it works fine on the RS.
The 6.5 mile climb into town seemed to take forever today(30-40 mph headwinds), but it gave me a good chance to get out of the saddle and mash on the pedals. The frame laughed at my puny power output.
The ride home was a high speed descent(48mph max)for about 4 miles and then about 2.5 miles of chipseal at speeds up to 40. My old Flyte would have rattled my teeth out at that speed, but the RS was very comfy.
So after my short test ride, I'd give it an A, pending any major quirks that pop-up next week when I get to put in some real saddle time.
