Hi All,

I downloaded On-Target and I've been tinkering around with it. However, I'm getting very confused. Here's my bow set-up:

2005 Bear Omni Pro
68# draw
29 inch DL
I have a peep, Sims leeches, and a loop on my string...not sure how much this weighs
I shoot a mechanical release
Using NAP Quicktune2000
Arrows are CX Terminator Hunter 6075. 28 inches long with 2 inch blazers, wraps, and 100gr. field points. Complete arrow weighs 446 grains. Speed is about 245.

I'm trying to use On-Target to find a lighter arrow. I'm looking for more speed and a flatter trajectory. I'd like to be able to use 1 pin for out to 20 yards, which is currently not possible.

Anyhow, I entered all the data and was pleased to see that my current arrow choice is perfect! However, I can't seem to find a lighter arrow that falls within the same specs. Also, I'm noticing that the "optimal spine" for my set up keeps changing. What am I doing wrong? Could some of you more knowledgable folks crunch some numbers for me and point me in the direction of a lighter arrow? I'm looking for around 380-390 grains for the finished arrow. 28 inches long.

Any help would be greatly appritiated!

Kind Regards,
Axel
