I shot a glove for years (killed a lot of deer too), but use a tab now. I found that without realizing it, while using a glove, I sometimes held the string with more pressure on my index finger, then sometimes realized I held more pressure with my middle finger. Don't know what made that happen and it's probably just me,,,, but it did affect my release differently each way.
Using a tab eliminated that problem for me. I also like being able to wear a glove and tab at the same time when it's cold.
Also, I bought some leather and make my own tabs which gave me the chance to experiment with different designs and thickness until I settled on the one I use now...
