Allright,

My vote for the occasional erratic looking flight is bad vanes. It's not a bad bow and I don't think it is tuning b/c at 10 yards to 30 yards, if I do everything right I will hit where I aim and the arrows are all consistently hitting the target at the proper angle (have not paper tested in a while though). I have had to glue a few of my vanes back on myself trying to match the existing offset (using 2" blazers). I also have a fletching that has a hole in it from another arrow. I will keep an eye out for bad flight and mark the offending arrow, and will pay a lot of attention when I start shooting broadheads again (soon). Learning how to properly fletch would probably also help.

Thanks for the info.
