i'm new to the forum and just got back in to bow shooting after 40yrs. of being away from it. does anybody have any feedback about a mathews black max 2 bow? i just got one the other day and it's a real bear to pull back. it has 70lb limbs and i've back them off 4 turns and still have a rough time getting it pulled back. my ultra max has the same poundage limbs and they are back off 3 turns and i have know problems pulling it back. i did find out one thing is that the bow string is an inch and a half longer than the specs call for. would this cause my problem. both bow have a draw length of 29.
