I was told by Ron that 7"-7 1/2" is recommended for his long bows. But don't be afraid to go a little above or below these recommendations. It really depends on the bow itself, and the string and arrow set up. I've shot mine at 6 7/8", and 7 5/8" with different strings and arrows successfully. The shrews are very forgiving in this regard. I had the same problem when I first got mine. I think he recommends the same for his recurves. Currently my long bow is 7 3/16", and my recurve is 7 1/2". Shrews are great bows! Have fun, and tinker until you find something that feels right. You will know when you get it.
