Not sure how tall you are or what your arm reach is like but I think overall (IMHO) If you go too wide you cross the line from extra stability into struggling to keep your arm stretched out too far to actually stay on the bar. I'm with you. 27inch seems to work pretty well most places and I think the only reason the 28 feels really good on the DH bike is just because it weighs 44+ pounds and the head angle is so slack the a little extra leverage just feels right.I chop mine down to 27" for freeriding, seems to be a pretty good balance. Tried to do the 30" thing and hated it.
hope the brakes are working!
I have not done any DH riding, of that caliber, looks like fun
Altitude? trail length?
