I like tabs better, but they seem to be a little more touchy when it comes to fit. As long as a glove fits snugly, I can shoot it fine, and it doesn't seem to matter if it is a reinforced American Leathers, or a thinner Dura Glove, as long as it is not so thin that the string hurts my fingers. Tabs have to be sized and trimmed very carefully in order for me to like using them. I don't like any overlap on the sides, and I like the ends short enough that they look too short when my fingers are extended. I am particularly sensitive about the part that covers my forefinger: the least bit too long and it's gouging my face, so I end up trimming a millimeter or less at a time until it is just right. If I trim off one millimeter too much, the tab is ruined, so I will agonize for days sometimes over whether I should trim one more millimeter.
I've never had the problem GCook mentioned about a tab not being wide enough to protect the sides of my fingers from the string. Maybe that's because I never shoot bows shorter than 58”, and my normal preferred length is 62-64”?
