Arrow set up / spine question

[Lawrenceu]

I'm going to have to try something I know very little about.  All I've ever shot is wood shafts.  I recently picked up a new bow.  It is an R/D bow that is cut to center.  It pulls 61# at my draw length (30").  The bow is sweet. But, all my shafting is showing weak.  There is nowhere near me that sells shafting and I don't have time to make any. So, I am considering buying some aluminum shafting.  I normally use 125 gr. Zwickeys on my hunting arrows.  Do any of you wise men have some suggestions on where to start spine-wise on aluminum shafts.  Also, I use three 5" shield cuts for fletching.

I would personally go to a carbon shaft but wood is my favorite... With a 31" arrow it will like a 75-95

You didn't say if your bowstring is dacron or fastflight. That will affect spine since dacron has some stretch in it and fastflight doesn't. At 61#, if you're using a dacron string and your arrows are cut to 31", measured from the bottom of the nock groove, a medium weight aluminum arrow would be a 2314 and for a heavy arrow, a 2216. These  sizes should also work for a fastflight bowstring and the key word is....should.

Thanks.  I have a Dacron string.

I'm hoping I can get these set up and tuned before the weekend.  That will buy me some time until I can get some woodies.

Build out your side plate-takes no time at all compared to going to a material you are not familiar with.
