i am shooting a Mathews HeliM 28.5 inch draw and recently bumped my draw weight up to 65# and i was wondering if my maxima blue 250s cut at 28.5 inches would be under spined for this setup? thanks in advance.
You may be under spined, charts give starting points but usually you have wiggle room on either side of a given spine weight. If you start getting funky arrow flite you could try a lighter tip weight. If you build your own arrows, use a heavy wrap as adding weight to the rear of the arrow will stiffen the spine as well( this would only be in the case of very minor correction)
I agree with cottontop. The charts are just a starter. Im a 30" draw length & have always shot 340 spine arrows. Even my 60# bows shot 340's. well I picked up a Bowtech Reign 6 in 60#'s & it want shoot a 340 spine unless I put 150gr's up front. Which with my current arrows is to heavy. So I had to go down to a 400 spine. I went with the Black Eagle Deep Impacts. Their pretty awesome arrows so far. Gonna start broad head tuning tomorrow.

With those I was shooting great wo th the 250s at 70# those are kinda different in how they fly for some reason as long as you don't stack alot of weight up.front you should he good Sent from my SM-G955U using Tapatalk
