OK, so I test rode a Giant Escape City early in the summer that had SRAM VIA shifters. The bike was fine, but the the trigger shifters felt "backward" to me. I can't remember exactly what the problem was, but the finger positioning seemed completely opposite of what I expected and the other bikes I had test ridden at that time (Specialized Sirrus/Vita, Trek 7.2 fx, etc.).
I mentioned it when I returned from my test ride to the part-time mechanic at the LBS who was helping me. He thought I didn't know what I was talking at first, lol, then he tried them and thought they felt "backwards" too in terms of finger movement on the triggers.
So my question is, is that just a SRAM shifter thing? If I'm considering a bike that has specs listing SRAM X.5 shifters, will they feel like the same configuration as the SRAM VIA? I mean, I guess one could get use to anything, but it's a concern.
