I'm new to the whole thing and these are some of my experiences...
Was recently gifted a Black Widow PCH- 65# @ 28''. My first recurve, so obviously far too heavy for me to shoot consistently. As a result, I bought a cheap used recurve off eBay here in Australia, with sets of 35# and 50# limbs. It also came with a leather glove.
I can shoot the 35# accurately without any finger protection at all. My release of the string is consistent.
At 35# with the glove, my releases are very inconsistent. It's like shooting a rifle with a terrible trigger. The glove takes away a lot of dexterity and feel and seems to hang up on the string and even cause my shots to go right a fair bit.
Have briefly shot the 50# limbs with my fingers and I seem to be more accurate, but my fingers start to kill after a few shots so I go back to glove. Again, inconsistent releases.
Shooting the BW at 65# is impossible for me without a glove but I find I can be reasonably accurate because the power of the bow rips the string out of my fingers quickly and allows for a more consistent release, all things considered.
Have ordered a BW finger tab and should get it next week. I'm very keen to see how it feels but I predict it will give me much more feel and consistent releases across the board.
