Some of you may recall that I had several posts here in the past few weeks whining about not being able to shoot a group with my broadheads out of my new switchback. Well, last night I was at the shop again, and the guy set it up just right, and said F**K paper tuning, I don't wast my time on it with these new bows...and he explained why. Well I got home and had the exact same problem. Well almost, The groups were tighter, but I was shooting with the Lumenoks, and I could clearly see that the arrow was not flying anywhere near straight. The arrows I am using are off of my old bow, they are CX 300 hunters,and are fairly short, the broadhead only clears the rest by about a half inch at full draw. I decided they must be acting too stiff being that short. I tried some of my buddies 30" arrows, but they were CX400's. They hit and grouped very well, but they had the same, spiral type flight. After I packed everything upI remembered that my dad has some 29" CX300's for his Mathews. I grabbed some of his arrows and set them up with my lumenoks and broadheads. I shot them a few times and BINGO! They fley perfect! They hit exactly where my field points hit too! WOOOHOOO! Its about time! The season is 8 days away, I was getting nervous! I can't believe that there is that much ofa difference between my 27" CX 300 Hunters, and my dads 29" CX 300's.
