I have an American Leathers glove and it give more protection than any of my others, to much for my taste but I'm only shooting 50#. It's a very well made glove.
I'd consider other causes than too thin a glove though. Sometimes a high draw arm elbow can put a little extra strain on the ring finger. You might also drop the deep hook on that finger, keeping it on the middle and pointer. Depends a lot on the length of your fingers but for me with 64" bows there is now way I can keep a deep hook on all three fingers without being up to the second joint on my middle finger...and that's the one that does the most work for me (I shoot split finger). My ring finger is on the string but more for position than anything else, it doesn't hold much weight. Good luck.
