Hi, I am thinking to buy a Sanlida Royal X8 longbow. The site which I want to purchase it from has the draw weight ranging from 30 pounds to 45 pounds, on the 68 inch bow. What weight would be recommended? I am 6"5 with a roughly the same wingspan and train lots of climbing, so back strength shouldn't (?) be an issue, but asking to make sure. I am afraid going with 30 pounds would lack punch as opposed to a higher draw weight.

Help would be appreciated!
