I'm a big fan of the Carter Quickie II Plus if you want a wrist strap release. It's a hook style, index finger, wrist strap release, but has the same mechanism as all their high end hand held target releases. Even has the external spring removal so you can try different release forces and has the adjustable free play screw.
I carry it around as my back up now, as I've started hunting and shooting target full time with my Carter Just Cuz and Insatiable releases. Got tired of trying to go back and forth between releases when the seasons switched.
Cheers,
Pete
