bow spine tolerance?

[Brad Arnett]

I've been shooting trad bows for a quite awhile, but I've never had much experience with a large number of bows.I started when I was about 18 and am 34 now and I lucked into my first good bow being a Wes Wallace Mentor; it fit me perfectly and I shot it for years without much exposure to much else. Now I'm at a point in my life that I'm lucky enough to start to be able to play with different bows more regularly and the first thing I noticed is that some are just much less finicky than others. By that I mean they shoot a wide variety of arrows compared to others.

For example, my 55# moab shoots all these arrows equally well.

gt 35/55 29" w/250 up front.
gt 55/75 28.5" w/350 up front.
AD trad lites 29" w/175-250 up front.

I also have a 50# moab that is more fussy. It shoots the 35/55 arrow good but not the 55/75. It does shoot the AD Trad Lite arrow with 250's, but does worse with the lighter points on it.

I've played with some Bear bows that seem to be pretty fussy with what they like. I've also played with one of John Mauss' bows that ate everything you fed it?

SO......are certain bows just more forgiving than others?????     :confused:

Some bows store more energy than others, and some transfer more energy to the shaft depending on pre load at brace and limb design.

A bow with more snap to it is going to flex that shaft a bit more.... the amount the shelf is cut to, or past center makes a huge difference too.

That's been my experience.

Maybe I'm missing something, but why would you expect a 50# bow to shoot the same arrow as an identacle 55# bow?

I have a 53# bow and a 51# bow that shoot the same arrow equally well (517 gr carbon 400), but I had to prove it to myself by tuning. But I also have a 50# bow that wants a completely different arrow (2117) than the 51# bow or the 53# bow. Strange, but it has all been confirmed by tune.

I think you are right, each bow has its own character or personality. And some of them can be very twitchy.

the more centershot or past centershot a bow is....with a clean release...the less spine is as finicky....and a stiffer arrow will be tolerated by a bow that by all other accounts should not shoot it well.

Eric, No i don't expect them  to shoot the same. We had 4 50# bows here yesterday and what we noticed was that some had a narrower range of arrows that they would shoot and one seemed to shoot good with every arrow through it. My original question was is it just an individual bow characteristic, or design?

The amount of center shot has alot to do with it.

Brace height too, your indirectly changing the centershot by adjusting the brace height.
