Hmm, interesting
you could alway try a finger sling... buy, or make one. Put your bow together & without loading an arrow, pull the string back a few inches, just enough to put a
little tension on the string fingers, then let the string-fingers relax, keeping the bow-hand relaxed. run this through for several times, until it starts to feel natural. It could take some time, but stick with it. Hope this helps.
