No nodog, I shoot a 340 at 29" out of my liberty at 67lbs. And its on the edge. If his draw is 29.5, then he would want to shoot a 30" arrow. Maybe 30.5". And 340 is too weak.
Interesting. I have shot the 340s with my 31 inch draw (30.25 inch arrow) and 65-70 pound draw weight range off and on for several years. I do not have the chart handy but I was under the impression that I was right in the middle of the 340 suggested range. It has tuned well enough for me over the years. Now you have me wanting to go back and check.
