If you plan on doing any competitive shooting stay away from the SQ2 and other short bows like it. If you have your heart set on Mathews I would get the Q2 but also take a look at some other bows as well, like the Champion Mustang, Bowtech Patriot, Mathews Conquest 2, Hoyt ProTech, and the Parker Feather-Mag II. Do NOT limit yourself to 1 brand because it is the most popular.
