RE: acudraw 50
I've got one on my bow. Never given me a problem function-wise. The handles are held together by magnets. The only issue I can think of is if you don't ensure the handles of fully retracted back and the magnets are sticking to either side of the stock, the handles can bang against the stock at an inopportune time. Just make the handles are retracted fully back and "sticking" to each other and you'll be fine.
