It is DEFINATELY a lot of trial and error...sadly a lot more error in my case over the first few years. Everyone I knew, most of the discs at the table at tournaments were 175g stable discs, which my throwing style was just not able to get to work right. I finally learned about weights, and found for me that 161-165g discs work best for me in backhand, and that 171-173 work best for me forehand <except my destroyers which are 168g>. Yes, wind will have effects on your disc, and you may want to keep heavier, overstable discs in your bag for just that. If you have friends who throw similar discs in lighter weights than what you have, ask to try it. In the past year I've probably gained 50-70 ft in my drives by going down in weight, and actually gained in accuracy as well.
