I Mostly Use a BaitCasting Reel for Bait Fishing Groupers and Red Snappers (Tranx 401 PG to be precise), so yes ... I Need my THUMB to feel the Line when Casting and also later to Feel the BITE and Also to Apply THUMB Drag on the FreeSpool while fighting the fish ...
For Casting Lures I use a Spinning Setup(Saragosa 6000, to be precise), and Use the same gloves but I add a Index Finger Casting Glove for Heavy Plugs and Minnows(To save my finger.
Alternatively, I use my Okuma Motif Full-finger Fishing Gloves for the Spinning setup.
However, Given a Choice, I'd prefer these Very Rapala Gloves for Fishing all Day.
