I'm considering making a yew takedown hunting bow out of some nice billets that I have. I'm looking at the sleeves that 3 rivers sells and trying to decide which size to get. The small sleeve measures, 4" x 1 1/2" x 1 3/16". The large size measures, 4" x 1 3/4" x 1 3/16". I'd like the smaller sleeve for comfort but I'm wondering if yew might need the larger size for safety. What are your thoughts. Also, are there any other sources that sell good take down sleeves?
