If you're interested in a challenge, why do you use 20# braid for crappie? In another thread, you said you used it in case you hooked a 30" walleye. Well ... why do you need 20# braid for walleye?
FWIW, I don't care how anybody fishes, but you can't say you fish for "the challenge" when you use line strong enough for tarpon.
Challenge is in the eye of the beholder. Just because you use bait doesn't mean the fish swim up to the boat and give themselves up.
The Keitech baits you favor have smell, flavor and texture cooked into them. According to my local trout regs, Keitech would be illegal because they are bait.
