Medium or hard cam?
 

Have never used easton arrows before and when looking at their shaft selection guide for FMJs, the first question is medium cam orhard/single cam. I shoot a Hoyt Razortec with the Cam and a half system. Is this considered a medium or hard cam? Depending On what I put in it suggests a 340 or 400 spine.

FYI, I shoot the razortec, 29 inch arrows, 100 grain heads, 64 pounds, with a release. 340 or 400 spine?

RE: Medium or hard cam?
 

When in doubt,go stiffer.It is a relatively hard cam.In your case,you are definately at the breakover point so always go stiffer in this case,which would be the 340.

What is your draw length?

Thanks, I was leaning that way.

29 inches

RE: Medium or hard cam?
 

340 is just on the stiff side but .400 is too weak for broadheads.

RE: Medium or hard cam?
 

If you use one of the arrow software programs like OT2 , it lists the Cam 1/2's as 1 cam hard.

I believe almost all bows now would be referred to as a hard cam. When in doubt, go a little stiffer on spine. From my past experience, the cam 1/2 system liked a stiffer spine.

Hard cam for sure.

I have a RazorTec as well and it is somewhat of a overachiever with respect to the KE it develops.
I would consider that a .340 arrow should spine just about perfectly for you if you leave it at about 29"

I shoot mine with a DL of 29" and 70# with .330 spine arrows at 28.5" and they tune about perfectly.
