Trolling is the only way that I fish for trout, I use a banana weight with a split ring and a swivel, followed by a gangtroll of some sort, (cowbells, ford fenders, beer cans ) usually in a 50/50 finish, I also put a split ring with a swivel on the end of that and attach my uncle wes to it ( my tackle company ) then bait it with a worm. The reason for the split ring's and swivel's, is so can change over quickly and resume fishing. I can change weight, gangtrolls, or wormtrolls with no fuss. Now with water temps being down like they are I would and do use silver blades on my worm trolls, it seems to aggravate the trout into striking, secondly don't be bashful about asking other fishrman how deep they are , how much weight, and etc.. most fisherman don't mind sharing info. You can try my suggestion's or not but either way I wish you good luck and keep on experimenting, the more time you spend on the water the better you will become. Also try reading up on the species of trout your going after and maybe a little home work on the particular lake your fishing.
