well i'll tell you what i know. itsa fred bear epic extreme from the first year they came out (2000 i think). i bought it used from someone i used to live with in MD just to get into bowhunting without the cost of new stuff. i took it to the shop and they set it up to fit me and never told me any of the measurements. the only things i can tell you that might help is that i have a WB rest and gold tip 5575 shafts. it shoots very accurately, just not all that fast and the last time i had it in they told me that the draw weight couldnt be increased any more.
