I am hooked on 5/16 inch thick laminated Maple. Very strong and light without a finish but edges sanded smooth. Have tried the Fat Bob type slingshots like 3/4 inch thick and I have found for my hand thinner is better. I would suppose any laminated wood is going to resist breaking at the fork even if you hit the fork. Any solid wood not laminated as plywood will break. After enough fork breaks I stopped using solid woods. Dont want to get a fork in the eye or anything that does not belong there. This is my 2 cents.
