i've never set a strat before, but i know if u go t heavier strings the extra tension will make the bridge pull out away from the body more. i heard you can balance it out by tightening or loosening some screws on the bridge. maybe (but i doubt it) you will need to reposition or add extra springs in the back of the guitar.

All this talk about intonation and adjusting makes me want to stick with 9's D: I thought 10's wouldn't be much of a change, but I guess it does. 9's have a lack of sustain *cry*
