Arrow help

[LUKE1]

I'm stuck between 2 of the Easton axis traditional arrow spines.  I am shooting a Damon Howatt Mamba 58# @ 28" at that draw.  Now I'm leaning more towards the 400 cut at 29"-29 1/2" with 75gr brass insert, a 125 or 150gr broadhead and 3gr p/i tube weight.  Total arrow weight: 580-605 depending on bh.  I am looking for opinions and what your set up may be.  I am currently deployed so I cannot tune my bow right now, but am soon to be heading back on leave just in time for spring bear season.

Opinions appreciated.

I assume the other option you're considering is the 340s.  .500s would be too weak.  .400s should work fine.  I'd go with a 100 grain insert and eliminate the tube weights. Remember to add another 25 grains for an adaptor, or more if you want to use steel adaptor.

I shoot 400s cut to 29 inches with a 100 grain insert, 25 grain adaptor and175 grain point ( about 590 grains) out of my 56# ACS. I do have the side plate built out a little.

A 550-600 grain skinny arrow is great plenty for bear out of your 58# bow.  Could reach 600 grains by substituting a 75 grain steel adaptor for the 25 grain aluminum. Might be getting a little front heavy for the spine at your draw weight though.  Only way to know for sure is to try it.  I like more point weight than weight tubes.  Provides the necessary weight and increases the FOC.  Good luck.

That makes allot of sense with the adapter instead of the weight tubes. Thanks!!!
