I normally hunt bare finger. Only because in Florida it is usually so humid during archery season my glove will get sweaty and start slipping off my fingers.
I shoot up to my 80# longbow bare finger, could probably shoot the 100# bow bare, but haven't really tried yet. Never have had any finger pain using bare fingers, some folks caution about nerve damage. I've never had any problems with pain, yes it does seem to result in better grouping at times but not always. You can always wrap your fingers with white surgical tape to protect them till their toughened up a bit.
I tend to shoot 10 shots then rest my fingers when practicing. Love hunting bare finger because it is one less thing to have to worry about if not using my glove.
Have never been able to use a tab, can't get use to the thing hanging on my hand and getting caught on things constantly. That's why I've always either used a glove or bare fingers.
