So far 13 votes for Bow-bolt and 19 for Locket-socket. To me anyway that says its pretty well split. Nearly all of the failures on the Bow-bolt were reported years ago, and due to using it in a straight wood riser, wood is an imperfect material and so that scenario is a no brainer.
I'm with Yellow Dog in that it gives you more options on grip shape.
*I have owned bows with both systems and I like both systems and don't really care which bowyer uses which as long as they are confident in it and know how to build it right.
Perun: you're getting a Java Man, that's been established
You can trust Gregg 100%, he's not going to build you a ****ty bow LOL, but an artwork, and it will work just fine with Bow-bolt or whatever system you and he agree to use. Of all people out there using the Bow-bolt system I would trust Gregg anytime, zero question.
