I can't find one anywhere, and my wrist surgeon looks at me oddly when I mention a concern for future hunting while we discuss her debilitating my right wrist next month during a necessary surgery. Of course I'm right handed.
I'll need one that would put the strain on the arm or elbow, and none on the wrist, though I will still actuate it with a finger, like now.
I presently have a string release, which has always felt great to use; better than dozens of others I tried.
If you've ever seen a special release like this, or have any info at all, please pass it on. And no, I can't switch-hit; that just doesn't seem to be in the cards.
