Hey husky
I'm not a gun on these bikes but my two mates I ride with are, turbo levos 29". I regularly ride outside of my comfort level with these guys. I like you enjoyed the improvement with the 27 and long chainstay chip not flipped, but didn't like the pedal strikes on my regular downhill trail. I could probably live with them however but considering going back and getting shorter cranks. I've only had a couple of rides with the chip flipped shorter chainstay, one pissing with rain, other wet. First trail was tight, steep, berms, rocks and mud. Normally I trail behind my mates but I was right on their ass this time. The next day I took it to my local tight downhill trail, sorry to say it gave me no special powers and I didn't really feel an improvement. When I bought the sam2 I trialled a jam2 at the same time. The jam chucked me off, I rode the Sam2 and felt like the bike would bail me out of the shit every time, just point and hang on. Moving to the fliped chip shorter chainstay on the Sam2 I'm starting to suspect I've lost that stability and confidence the Sam gave me over the Jam. Two rides is really too early to tell and I'll feedback more when I have more rides on it.
