Anybody has experience with short ATA bow and can give mesomesuggestion on how to solve this problem?
yes. Get a different bow.
bigcountry nailed it. Sell this one and buy a bow with a 34-inch-ish Axle-to-Axle dimension.
Right at the start of the 2007 archery season, I got a Mathews Switchback XT (31" A-A) and never really got comfortable or extremely accurate with it. I don't think I ever could have, either, with my 30" DL. I solved all my problems by following the above advice. My two bows are 34.5" and 33".
