Damn....hope everybody is ducking or bailing out of the way!
I'm 5'8"ish, about 190 (about 10-15 lbs more than I should be
) and the best stick I had flex-wise was a Ryan Shannon pro stock - 82 flex Bauer. I always found 85 flex sticks really almost were too stiff after they are cut. But I do find the 75/77 flex to be perfect. I could never go to an intermediate flex - plus the stick is too narrow. Flexing a 55 though..... would be like playing with a wet noodle.
Shooting is 95% technique. I find it humours that there are people I know (well, at least have skated with over the years) that think no matter how poor their technique/ability if they get the best stick around they are magically going to be a great shooter. (Note - I am not saying that is applies to this thread - was just stating an example)
