The system I use for BH' s takes a little time, but
works very well for me.

1. First and foremost, make sure my bow is properly
tuned and shooting well. Before I went to a drop
away, vane/fletching clearance always seemed
to be a problem. It' s possible to get away with rest
contact with field tips, but BH' s can be a different
story.

2. This should go without saying...make sure arrows
are of the correct spine.

3. I number each arrow and BH.

4. I then proceed to find which combinations fly the way
I want them to. I save old blades that I have shot
before and use them with the new BH' s...that way
I' m not ruining new blades and can save them for
hunting.

5. Once I find a BH and arrow that fly well, I set them
aside for hunting only. This is a combination for
the life of each...if I use the arrow in the field, I just
replace the dull blades with new ones (unless of course
I hit one of those big rocks in Arizona, which I seem
to do every year[][:@]).

From my experience I seem to get about 4-6 out of a dz.
arrows to match up with a BH. I' ve used Muzzy, Wasp, &
Thunderheads over the years, along with Gold Tip & Easton
ACC arrows.

I use the arrows that I can' t match up (get to fly right with
BH' s) for 3-D and shooting practice.

Hope this gives you some ideas and Good Luck!
