What Surewood shaft for my Shrew?

Kevin Winkler · August 24, 2010, 01:20:00 PM

I have been wanting to try some Surewood shafts and I'm not sure what spine I should get.
I shoot a Shrew Classic Hunter 54" 53#@28" foam cores w/carbon.
My draw length is 28.5" and I cut my arrow at 29.5 to BOP and generally shoot 145 or 160 grain heads. Any help would be appreciated!

70-75 should be a starter for You...

If your Shrew has the 450+ string on it, plus the carbon/foam, with a 29.5" shaft you'll need to go to 75#+.., deflection of .325@ 26" or .400@ 28"

Thanks for the info. guys! I'm going to have my wife mark my arrow after I shoot a little tonight, I'm going to see if I need the 29.5" or if I can cut a little more off.

Ron, If I end up cutting my shafts shorter, would I drop down to a 70-75 spine?

It depends on how much you cut off and what your actual draw length is. Check it and let me know

My figures come real close to Ron's, and I will defer to his experience with the Shrew. I'm not very familiar with the foam cores but can see where they could affect spine.

Good choice on the Surewoods.

I checked my draw last night and I'm at 28.25" draw and the shortest I can cut my shafts to BOP is 29.25" if I go any shorter the back of the broadhead will hit my finger.

In my very limited experience I would say go with the 70-75's or 75-80's. My Shrew Scout shoots 65-70's just like Ron said it would. Mine is 55 @ 28" and I draw 27". My arrows are 28.5 BOP with 160 Treesharks.

Heh Fletcher, since these are Surewood firs does that add another 5 #'s since fir does not recover quite as fast as POC ? If so he should be right on as you and Ron said with 75-80's ? At least if he is to the high side he can leave another inch of length on them if needed. If he went with 70-75's he might get too short before he is stiff enough ? Better yet, order a test kit from someone in 65-70, 70-75, and 75-80, THEN order 3-4 dozen shafts and start making arrows or order them from Fletcher. Fine gent and even finer arrowsmith IMHO !!!
