I don't know,most of the people I've seen that use a finger sling are recurve shooters that shoot from the web of their hand.I like to shoot longbows and especially Hill's.I hold the grip firm and heel,like carrying a suit case.I prefer a longbow grip whether it is straight,dish or a mild locator.I just never really cared for a recurve grip.So I don't see that a finger sling would help me,because I like the low grip and heel the bow.I guess it would depend on how you hold the bow,but I've seen longbows with recurve type grips so maybe.
