I am purchasing carbon express maxima 350 hunters. 68-70# and 30" draw using 100gr field tip. What should I have the arrows length cut to for the best spine?

Thanks

Thats a question that cannot be answered without actually 'being there'. Depends on bow design, rest location, etc.

Ok. For some reason I thought I read a software that could show the best length cut arrow given the specs on the bow?

it is a parker hunter mag extreme (but I do plan on buying a new bow within the next year). Well if you mean the rest location compared to my brace height, I could probably get by with a 29.5" and still have .5" arrow or little more past the rest.

Thanks little. I will use that.

I had actually thought the some of the software available could calculate what the best arrow length would be for your set up to have the best spinned arrow. I guess I will just use the standard way of determining the arrow length.

They list a "Windows Software", and clicking on "Infor Guide", you can purchase a CD or a Download version. Lots of information by clicking on the boxes. I remember having a program years back where one could change arrow length, bow poundage, different size and length of arrows for different results. Hope this helps.
