alll around trail riding….well, as for drivetrain, i'd actually have to say go sram for sure, X.9 with X.7 triggers works great, the X.9 triggers aren't necessary. XT brakes are very nice though, you'll want to stick with those unless you decide to go magura louise or avid juicy. RF evolve stuff is decent, nothing spectacular, but it works. if you can get a hold of some shimano hone cranks, get them right away. XT cranks will definately work for you too, they're really strong. for the bars and stem, if you want evolve go for it, i'm not sure what your budget is for that stuff, but there are definately better choices like an answer protaper on a thomson stem if you really have the cash. easton ea70 bars are light and stiff and easy on the wallet too, and you could pick up one of the havoc all mountain stems to match. the recon is an ok fork, i'd definately recommend something different. the rockshox pike is much more versatile and still somewhat light, about 4.9 lbs for the U-turn version of the 426, which puts it lighter still than the fox 36. if you can get a 36 talas though….mmmm. hope that helped.
