I'm havinga little trouble with my arrow patterns, a lot actually. My arrows are hitting sorta tilted to the left and I'm shooting 18" groups at 20 yards, thats not a typo. I've had it tuned at the sport store that I bought it and it hasn't made any difference. I did notice that the whisker biskit is tilted down a little, so its not quite perpendicular to the arrow. Do you guys think this could cause whats going on here?
