So after bothering you guys and finally getting ontarget to say my arrows spine is fine like it was for ausie and t-labee, I decide to give it a shot in TAP. I'm still trying to figure out which one I want to buy. So, first ontarget tells me my arrow is too stiff, and now TAP tells me its too weak, puts it right on the red. What is up with the opposites here? I am 99% sure I'm entering all the info right.

all programs, spinesharts etc. suggest a stiffer spine than you need.
i use ontarget2 and just love the program, it makes dead accurate shighttapes etc. but for spine you can use what it says but you can go softer too, but you will have to try that onn out your self.
I shoot Navigators 540 at #55 and 29,5" and according to any shart i´m way underspined, but in reality it works great.

The output of the software is only as good as the data you put into it. I have been using TAP for years and have been able to generate some pretty poor sight tapes (bad data in, bad data out) and screwey readings for my arrow spine, trajectory, etc.... That being said, when I do my part and get the readings right, the sight tapes and everything else is dead on the money.

While the arrow selectors tend to recomend a spine that may be a hair on the stiff side, you should be fine with anything that is in the yellow on either side.

With respect to the programs showing the same arrow in the green on one and the red (weak) on the other, I would have to say that you probably have something out of whack. When I did my comparisons I found that TAP and OT2 seemed to be pretty close with respect to their readings.

I have found...

it is extremely precise. BUT as Redline says...you have to be exact in the way the info is entered. The software it self is kind of tricky to use, and it is very fussy...and should be... or you won't get the desired results.

I would suggest that even if you don't buy or use either piece of software...use this resource (archerytalk) to have someone help. Unless you are going to help others set up their bows... Do you need the software?

If you want to learn it...I can try to help...
