just a little help

I have a 45 lb ko-mag, and was wondering if any of you guys might be able to help me with arrow setup. I have some cedars, and they fly great. but i want some aluminum ones and i know nothing about trad arrows.
27" draw btw
anything will help
thanks

 

Live, play around with this spine calculator. It got me in the ballpark and then I tweaked my set-up to fine tune.

1816's or 1916's assuming your going to use a 125 grain head.

 

should i look into a heavier head or maybe some Heavy Inserts? I was thinking 125 or 150

 

I have a 45lb Grizzly that really likes 1916's with a 125gr point. My draw is 27" also

 

awesome....1916's it is

 

My arrows are cut to 28.5". You might want to leave them full-length at first then cut to size as needed to tune. I also use 4" feathers so if you use a 5" fletch, that may make a differance in the OAL

 

the hardest size aluminum arrow to find haha
might have to go to three rivers for this one.

 

ok ok. this is hard to accomplish. all the archery places in the tri county area and i cant find 1916's lol
