I was recently given a Hoyt Fast Flite Super Slam this is my first bow I have ever owned. Im interested in it and would like to lean more about bows. From research I have learned this is a compound bow. What im asking is that if anyone with any type of general knowledge with bows can inform me on bows/compound bows any help is appreciated. Also when I try to draw the bow string its very hard and requires alot of strength how would I release tension on it or is there any place I would take it to have the tension released.

Thanks
Justin
