It has to do more with casting heavy weights, than proper form. If you want to try to tell me that I don't have good form, you're going to get into one hell of an argument
3 oz is about the lightest weight that I cast. When you move up to 4, 5 and 6 oz, you need something on your finger. Especially when it's raining--wet skin cuts way more easily than dry.
Braid is abrasive--all brands--even the soft ones like Sufix. After a night of throwing 4 oz jigs with a reel like a 525 Mag or a Saltist, my leveling thumb looks like raw hamburger. Retrieving eels and light plugs doesn't put nearly as much stress on your thumb as humping 4 oz jigs from 40' depths against a 4 knot current does. Same is true when you're talking about casts with a spinning reel. Once my leveling thumb is junk, I have to switch over until the skin repairs itself--if I chew my trigger finger up, what am I supposed to do--not fish?
