spine ??? CX90 vs aluminum

[ronp]

Does anyone happen to know what the spine is for a CX-90 Carbon Express, and, more importantly, what aluminum shaft is equivalent?  I shoot #43 at 27" draw.
Thanks - ronp

The heritage shaft is .530 spine. Not sure what aluminum shaft is equivalent, maybe 1918 but they don't amke it anymore. Are you the same person from the b@#s#$e that asked the same question?

Thanks Jr.  I do not know what b@#s#$e is.  Please enlighten me.  This is my first time asking a question regarding the CX-90s. Oh, and so you aren't confused, I use the name ronp on all the boards that I frequent.

The CX 90 spines near identically to a 2016 aluminum.  They won't necessarily cross straight over without a little tweaking though, the personality of carbon and aluminum is different but they certainly should be close enough for you to tune.

I would think a 2016 or CX 90 both too stiff for 43# at 27" draw unless your bow is cut well past center.  Have you tried anything lighter spined yet?

I think a CX 90 will be fine out of your bow with a 125 grain tip if you leave the lenght at 29" never tried one shorter.

Thanks guys.  Slowbowin, I have used 1916s and they shoot pretty well.  I have a dozen new 2016s legacy shafts that I was thinking of trying.  I didn't want to cut them or start making up some arrows if they won't work.  I think I could trade them for something lighter.
