I've got the bethwaite system on my a-cat. It takes some getting used to. It doesn't have the positive click feel that a metal ring or trap handle does. I find myself looking down to make sure I'm securely fastened before I trap out. However, it does a good job of not damaging the boat.

I've also got the RWO system on my distance harness. It works extremely well and has a plastic retaining clip to keep from losing the hook if you do have to hit the panic button. I also keep a spare hook in my lifejacket pocket. I've released the hook several times, but haven't lost it yet. I've used the RWO on the Tybee 500, and several steeplechase 100's, no problems so far. My only complaint is that the RWO spreader bar is not as wide as others, and causes hip pain after 6 - 8 hours on the wire.

YMMV
