RE: tab or glove?
I used to shoot a tab, many many moons ago. I've been using a glove for the last 8 or 10. I tried a couple of tabs again a while back, but they just feel foreign to me now. If the tab still feels good, go with that. Some folks get a better release over a glove. They are noisier for hunting, and I find a glove more convenient, but that's just me.
If you get a glove, be sure you can try it on first. Get one that fits very snug at first--by the time it's broken in, it will fit just right. I say try it on first because they can vary in size quite a bit. The only exception I know of is an American Leathers glove, where you send in a trace of your hand and the glove is custom made to fit you--and if it doesn't, just send it back and they will take care of it.
I have shot lots of different gloves. Damascus used to be my favorite, but they wear out too fast. I have used several different deerskin gloves, and they worked ok. The ones I currently use are a Superglove from Alaska Bowhunting Supply and an American Leathers Big Shot Slick Shot. Both require some breaking in, but are great gloves and very durable. Again, I would not buy the ABS glove via mail order--you can find a vendor that will have them at pretty much any big shoot (Cloverdale--hint hint) that will let you try them on. The last time I bought one, I probably went through 2 dozen or more before I found the one that fit properly.
