Range- if you do decide on a Merlin of any kind, be very sure of your AMO drawlength. They ship their bows VERY close to your ordered length, if not right dead-on. I have not seen any fudging of draw lengths with Merlin, and the three Merlins I' ve had all were beautiful to pull them out of the box, draw them back, and have them be just what I ordered.
Whatcha order is whatcha get.
Also, be sure to give PW12 a note to order your bow...... He' s the best!
