Spine / Centershot ?

[Curtis Haden]

Does a centershot bow typically   require a stiffer arrow than a non-centershot bow?

I realize the centershot bow will be less critical of spine, but does it go both ways?

I have a 52@28 Griffin, that I can shoot 2016's, tip-loaded 2018's, and tip-loaded CX 150's out of.  The shelf on the Griffin is cut   almost to  center, but not quite.  I also have a 50@28 Acadian Woods Tree Stick ordered, and due up in the next few months.  The Acadian Woods riser will be cut 3/16" past center.  I'm wondering if I can shoot the same ammo, or if I'll have to get some new, stiffer arrows.

Of course, I will test all this theory when the new bow arrives, but until then, all I have to do is wonder about such trivial matters.     :rolleyes:

Humor me with some opinions.     :cool:    

I'd actually love to be able to shoot 2020's (heavy and durable) but I'm afraid they'd be way too stiff.  BTW...I draw right at 28" and usuallly cut my arrows to 29" or 29.5".

Usally a bow cut to center or past center will require a stiffer spine.But the arrows you are shooting with the Griffin may work out for you also.You may need to adjust the point weight alittle.Carbons seem to me to be adaptable to many bows in slightly different poundages.Give them a try and see how they fly for you.I think the 2020's may be too stiff for the poundage you are shooting.I shoot 2020's out of a 65# longbow and they weigh with a 175 gr. point at 630 grs.

Also carbons respond to length more than point weight changes....

It is not so much that it is required, but rather you CAN use a stiffer spine.  The arrows you have will work just fine.  With some bows cut past center you may have to build out your strike plate.

Curtis:
Once you get to the minimum spine required for your Acadian woods you can go way over spine and they will shoot fine. At 29" I'd start with spines of 70/74@28" that should be minimum. 2020's spine 77@28" should fly like darts as they say.

Thanks for the feedback.  Bob and Paul really got close to the crux of what I was trying to ask...

Do you have a "minimum" spine for a given poundage, which will still work, regardless of riser design?  It seems intuitive that an arrow which flexes enough to get around the riser on a non-centershot bow, might be too weak on the centershot bow.  By the same token, it seems the arrow would still react similarly on the first instance of paradox (at the same or very similar draw weight) and then recover at the same rate...

I'm probably making this too complicated, considering I don't have the bow yet, and just making excuses   not  to call Tim (yet again) and ask, "Is it time???"      :confused:  

Does it make sense to try to understand paradox?  ...Only the engineers at Easton know for sure...
