It can also be the kind of retrieve you use, even with plastics. Last Saturday night a buddy of mine who usually catches fish only caught 2 small non keepers while I caught 9 keepers that we know of(we quit counting after this) on the same exact bait. He finally noticed the retrieve I was using & figured it out .lol. I sure wasn't going to tell him as we usually have a good friendly competition & the guys at work are always asking who spanked who & it tears him up to have to tell them I gave him a good one especially when they never let him live it down lol
