Does anyone else use this program?
I have it, and lately i have been trying to spine some arrows for a PSE Laser 2 finger bow (yea its old with round wheels and all) but it shoots great. 46" ATA 9 3/4" BH 64#
This program is telling me to use a Easton axis FMJ 300
To me this seemed a little stiff. What do ya'll think?

something doesnt' sound right at all. You sure you dno't have the sync button hit? It recommends with my 43" ATA 70#, 7.25" BH PSE with a 29" arrow a .37" spine.

What values are in the "Arrow point" section?

I have 100gr. point listed w/ a 16gr. insert. The sync. button is off i believe because it says sync not un sycn.
I have a 30.25"arrow plugged in.

Could it be that i don't know the AMO or IBO speed of this bow. I can't find any info on this bow due to it being so old.

What is the IBO speed that is being used? I suspect that it may be to high. Perhaps you could try and find the specs of a similar bow and use that IBO speed. Also, is there any way you can shoot a known arrow through a chrono and then punch those numbers in? That should give you an good, approx IBO speed to work with.

I am using 190fps, and 20% let off. for right now i may have to try to find a similar bow and use its speed. I am at college right now so i don't have any access right now to any of the equipment i need.
Does 190 sound high?

If you are using 190 I don't see how the program can be giving you a 300 spine. I am with bigcountry, something is not right.

i'm not sure the FMJ 340 shows up green in the list it gives you at the bottom right, but when i click on it the indicator on the top right of the screen shows that it is way week.[:@]

Haha i think i got it the sync wasn't hit so when i clicked on the arrows highlighted in green on the list it was telling me that a 340 was too weak and a 300 was just right. Now it is the way it should be with the 300 being too stiff and the 340 being just right! But it is still telling me the optimal spine of my setup is
