one small 200 acre lake i fish is a cold lake and i usually cant get bit until the fish come up. I usually never use anything other than 1/32 there. Another deep resivior all depends on the wind and current i fished 3/32 alot the last trips. Its probably a tad more important to me to have the lightest line usually 4# but i will be switching to 6 this year. I have good feel with 4# or 6 with the heavier jigs. I loved the feel of 2# jigs dropped like rocks, but broke off way to much.
