Well, guys, I learned something today. When I got my Shelton, it came with a string, so I just strung it up and started to shoot. It braced at about 7", so I figured that was where it needed to be. I worked on grip, swing draw, etc. It shot great, but there was some hand shock, especially noticeable after shooting my Kanati.
I made a skinny string, thinking that would help like it did with my Mahaska. It helped, but not quite as much as I had hoped. I was stumped! I had the string braced at about 7" or just under, like the one that came with the bow. Then I read a post by mikebiz in the HH thread about bracing his Hill bows between 5.25 and 6" so the arrow had more string time and hence more cast.
I thought it couldn't hurt, so I started to unwind my string and shoot. At 6.25" hand shock was noticeably less. At 6" it was essentially gone! I'm now at 5.75" brace height. I have no noticeable hand shock, the bow is still quiet as a mouse fart, and I may have picked up a bit of speed as a bonus!
Ain't life grand!
