im 6 4 and 16 stone
ive got a 2008 enduro sl in LARGE with e150 forks and it is superb, climbs fanatstically, descends great, never complained in the italian alps in summer, very light, and looks great IMHO. i bought it as a frame and fork package for £1400
i used to have a new style yeti 575, and did not like it at all, the back end felt very flexy under pedalling, i know 2 people who have snapped the carbon rear end, so i would say if you do pick the yeti go for the alu version. i sold the yeti after 4 months
for me the deal breaker for the enduro is the 5 year warranty on fork/shocks, i have returned the fork once for a new cartridge when i first got it, but since then it has been great, and spesh nevr complain about returns
