Nice buy, are ya going to put that combine bow away for good. The magnum is a short bow and alot of guys say they are to short, but I have no idea, never shoot one. I have herd they are good in thick cuver. I have a 58in griz that my dad paied about $30 in the 70s. I realy like that bow it to is a 45 at 28. Someone else will have to help ya with the tech stuf.
