Spine Question - Heritage 250's and 350's

[8leg-lover]

Hey Gang,

I know the gpi is different on these two arrows but are they spined the same?

Thanks and Happy Hunting

350s are stiffer

250's are spined 0.373"
350's are spined 0.320"

I have found with my bows that if I take a 175 grain tip or broadhead on a shaft cut at 29 inches for both 250 and 350's, I use the stock aluminum insert for the 250's and a 100gr. brass insert for the 350's they fly just about right for both. 250's about 570 gr and 350's about 670gr. With my 61#@28" bows I'm pretty happy. I probably draw slightly less than 28", I havn't rechecked my draw length lately or since I changed my anchor awhile ago. I also use the 150's with a 100 gr tip when I want bullet like speed! This is why I like the Heritage shafts, so much versatility, same components. When I go down to 55-56# bows I add 225-250gr tips  and my arrow weight increases to about 740gr with the 350's and a 100gr. less with the 250's.

I love the CX Heritage. My bows are in the mid 50# range. My draw is 30". I use he 250's. Have one 40ish bow use 150. and my 64# longbow 350's.
If you are tuning for your Hoots there are a lot of people who tune 150's with "dart" like flights.
