I don't want to turn you away from Mathews, but you sound like you're a new or soon-to-be shooter. If so then you need to find out what draw length will fit you or at least be close (within 1/2"). Then when you buy a bow make sure that it's adjustable for draw length, either by use of a rotating module or changing the mod itself.
Most Mathews bows are draw length specific, meaning non-adjustable. You can tweak them a bit, about 1/4" + or-, by twisting the string and/or cable, but that's about it. To change 1/2" or more you'd have to find and buy a new cam and sometimes new string and cable. Upwards of $135 + installation.
Hope this helps some.
