rubber float stops OPINION ?

Size or type -----  for scaguar fluorocarbon 10 lb leader ?  that will have a better grip on the leader ------- how about a carolina keeper? any good?

The bail rollers on the newer reels won’t allow that rubber stopper to pass through.any problems with the tube type?      Thanks.    CARPIO 

They work. Eagle Claw makes different sized ones. Still, I usually tie my own. The smaller rubber ones even work on 2# test mono. It's hard to find stops that work on some of the slick poly lines. Many of the pre-tied packs of stops on those little tubes also work just fine.
