blade size will also change depending on trolling or casting. we use alot of willow blades on ours when we troll. but speed is part of the factor......the willow blades work better and spin right at the summer trolling speeds in mid 2 mph, sometimes at those speeds some of the bigger blades blow out and don't spin right. our trolling harness use 3 hooks. 2 singles and a treble at the end. some days we do shorten the worm up if we are getting short hits.

and some times it's just which day it is.

dont forget also do you use 1 blade or multiple?????
