PMAII SPINE HELP

[Doubledrop]

I am looking for suggestions for my pmaII.  The bow is 60lbs at my draw length of 27".  I would like to shoot a 125 grain broadhead.  I have some gamegetter 500s that are full length can I make these work.  I also have some vaporwood 3000 carbons that I can add 100 or 50 grain brass inserts to.  Need suggestions, someone with a dynamic spine calculator  please help me out.
Thanks
Chris

the 500's may work if cut to 28".

Do you think the vaporwood carbons would be to weak?

not familiar with the carbons you are talking about. can't help there.

try Stu millers dynamic calculator may help get you in the ball park.. I have tuned a few combinations using it so have others on the site.

what about a 2117 what length?

I have the same bow and your draw.  I use 2018's at 27&5/8 with 125 Razorcaps.  The same bow will shoot 28" 2315 with 150's of the same broadhead although it helps to add a couple of brass weight collars.  Have not moved to carbons yet but will shortly.
