Back to square one..........

Well, I was pretty set in my ways about a 200 grain broadhead, this n that, yadayadayada......until tonight.

I went downstairs and didn't like the way the wool silencers looked on my string - too big for my taste.  I figured I'd cut them off, wax the string, and see what effect it had on my "spine".

I start shooting and now everything, I mean everything (even 3555's with 250 grain points) is heavy tail left.  I put on some string leeches quick to see what effect it had and it got a littel better, but not much.

I can't believe the degree to which silencers affected my bare shaft arrow flight. I now need to order the silencers I think I want and set up everything just so before choosing a shaft/head combo.


I always knew I was supposed to tune after all else was set, but the change has me very surprised.

I know how you feel....there are so many things that affect good arrow flight....good arrow flight is determined by the spine of the arrow...check out thid link....it's an aricle on spine....after reading it...my head was spinning...

Yes, that is an excellent article explaining the many things that affect dyamic spine. Although I didn't see anything in there regarding brace height. We all know there is a sweet spot for brace, but in many cases a change of 1/4" brace doesn't change how the bow shoots, sounds, or feels.... but it surely changes the dynamic spine of the arrow.

Here is something interesting to try Fred, with that arrow that is now on the weak side of spine. Lower the brace height some and see if they act stiffer and get back closer to where they were. I have done this in the past where I've changed broadhead weight slightly and it actually corrected the difference by brace height change alone.
