Went to the club today and am struggling with a consistent release. Sometimes it's perfect to the extent I hit two X's in a row, then missed the target. I can hear the string on release and it's a dull thud not a twang. Clearly some of that is me, but it happens a bit too much. Trimming the tab has improved it considerably, but I can't help wondering if the underlying problem is too acute angle on the string when drawn. At the moment I have a 68" recurve take-down with a draw of nearly 30", measured from the root of the nock to the front of the riser/handle casting. I bought it on the basis of a crude chart which compared it to my height (5'10"). But looking at other people in the club they seem to have far wider angle on their string because they are 6" shorter than me with the same size bow (French are short). I think I should be using at least a 70" and that is part of my problem, or am I being stupid?
