Ahahahaahah

 If I have to be honest that's the second bike I've ever tried so I'm not really able to tell you how the frame perform to be honest.
I can tell you the differences between this and the two other bikes I have but it wouldn't be a fair comparison I think

 The only thing negative I have read is some rear end flex. I'm tempted by these frames, but don't like any flex! Have you noticed any?

 Nothing to be honest.. I found a difference when I switched to carbon wheels. After that for sure I noticed less flex behind but it's more in the wheels. With carbon wheels I don't feel any type of flex

 I would like to help you more but I can't, sorry
