I got my alphamax 35 last night. Set it up super quick. Put a peep and D loop on string. Mounted rest and sight and shot perfect bullet holes. Didnt need to adjust center shot from my 38 Pro. The bow has a very little vibration in it. Super quiet and quick. I am shooting a 28" draw at 65 lbs with a 340 grain arrow and I got 301 FPS. It has the # two cam on it. The calulator says I should be about 289. Its over 10 feet faster with stock strings. Will I gain anything putting on aftermarket strings?
