Whatever it takes
Actually what I really like about the shrews is the forward handle of the bow, and the grip looks ultra comfortable with maximum pointability. There are many such forward handle r/d long bows out there, I just like the lil' favorite due to it's pop up blind friendly 54" length. Of course I have my bear supermag to handle that duty, so if you wanna start about 60" on a r/d forward handle long bow...
