Honestly I don't understand the hype with the Matthews bows. Not that they aren't any good - they truely are. But Matthews are great at advertising. They put a lot of stress on the Helium at 3 1/2 pounds, IBO speed of 332 and ATA of 30"and $959 MSRP.
I just picked up a Martin Exile for my cousin's son which has the following specs.: 3.4 lb, IBO 320, ATA 30.5", MSPR $639.
I truly believe that you pay a couple hundred dollars just for the Matthews name. I have 3 Martin bows and they are fast, smooth, quiet, delivers zero hand shock or vibration, and is extremely accurate. And their warranty and customer service IMO is second to none.
