I use 10lb braid on spinning gear, 20lb on casting.
I use leaders anywhere from 6-15 lbs on all.
No problems. I've caught 6 pounders on 6 & 8lb test
line on spinning gear. You learn how to play the
fish. I've caught beasties in sticks, stumps, downed
trees with all the above mentioned.
If I'm really concerned about the sticks, I'll put on
15 pound test. It's all about what you feel comfy
with, and we've all got opinions on that.
