Need spine help??

[3Feathers]

Want to switch from 135gr. broadheads to 200gr. broadheads.Shoot 45/50 spine arrows out of my Hill bows and was wondering how much more spine would I need to shoot the heavier broadheads.My set-up now is 27in.arrow with a 25in. draw.Will 50/55 work???

My guess would be 60-65.

Don't know what weight you're shooting, but given the rather short draw length, 10# spine wt. increase should do it, i.e., 55-60#.

My bow weight is 46-51 lbs.

Orion has it right.......55-60 should be perfect. I shoot ff strings on my Hill's with 48 to 50 lb draw and 25 1/2 draw length. I shoot 60=65 spine for 200 gn head. If your bow likes 45-50 with a 125 gn head, then 50-55's for 160 and 55-60 for 200.I take it your shooting a dacron string on your hill?
