for the life of me i could nt figure that omen out.some own them and do just fine but others like me and the new owner seem either not giving omen enough time or i guess we dont know anything about archery.the latter is probably not the correct answer.we had bow checked out and all was right on the money.i hated to see a bow that fast go but after a while it got old.i have an 18 yr old pse sitting here that will still get r done just not as fast as new bows.all i wanted was a 1 pin,fast,flat shooting bow.forgiving,it was not.glad you like your axe,excellent choice .if i ever get rid of bowmadness the axe 7 would be my choice.friend has matthews z7 and its a good one also.i hear the hf cam x forces from 08 were good but the hf went out the window when speed took over.good luck hunting and shooting .
