My '06 Allegiance showed up. I ordered it with the fast cams at 80% letoff. The pro shop never said a word about anything when I placed my order. When it arrived I asked them to make sure it was at 80% or as close as possible and he told me that you MUST use the smooth cam to get 80% letoff. Is this true? You either order the fast cam = 65% letoff or smooth cam=80% letoff??????? This pro shop in not very technical and basically handed me the box and said good luck. This is why I ask. Can anyone say they have the fast cam AND 80% letoff. Is this BowTech's position on this. Thanks for any advice!
