Thanks for the good word men!
First, I can't take credit for building the bows. Marc Moriez is the bowyer, and they are still made in Abbotsford, BC where Chek-Mate has been located the past 34 or so years. I'm just a dealer (CM doesn't sell direct--only 4 people at the shop, one bowyer, so they don't have time to take care of customer service), but I do make the strings for the bows I sell.
Properly tuned, they are very quiet and have very little hand shock. Some say "none", but to me any bow will have a little. Get a bow that fits you, and there will be no stack. 'Course if you draw 32" and try to shoot the 52" Raven, it's going to stack, but if you draw 28" you can shoot it just fine. If you do draw 32", there's a few models that will work for you also.
Accuracy is in the shooter--if you mean how forgiving are they, it depends on the model. All are forgiving in some aspects if you get the right bow for you. For example, if you have a habit or torquing, I wouldn't go with the Longhorn, because with it's reflexed riser it's more sensitive to torque. The Attila isn't going to be as forgiving in arrow spine as the Hunter II because the shelf on the Attila is cut to center, but the Hunter II is cut past center.
In my opinion, they are excellent bows for both beginner and seasoned archer. My best friend has taken more animals with a bow than anyone I know personally, plus several trophies when he shot tournaments, and he shoots the Falcon (he has 3 or 4 with another on order).
The "official" warranty is 2 years against defects in material or workmanship. Full warranty, not pro-rated. After that, it is at the descretion of Chek-Mate. I know they have taken care of a lot of bow that were well beyond the warranty.
Hope that helps--if you have any questions feel free to e-mail or call. Both are on my web site.
