Go with whatever brand carbon arrows that you want.

I prefer GoldTip Pro Hunter shafts. They are weight matched per dozen and are the straightest andtoughest carbon shafts thatI have tested.

I also likeMuzzy broadheads - 100 grain, four blade. Yet to bend one and the wound channel rivals most mechanicals. I am going to play with the NAP XP cut-on-contact Thunderheads, 100 grain to see how they perform on my arrow disentegrator.

I say go with the brand of choice, but you have to focus on spine strength most of all, given the following suggestion:

Go to www.3riversarchery.com , this is a traditional archery supplier, actually the largest in the world. They also have a "working warehouse" that you can walk through and shop to your hearts content.

There you can search for Weight Tubes 6731-1, 2 grains per inch or 6731-2, 3 gpi. NOTE these will not fit the Easton AXIS shafts.

Sidebar: I have received a number of complaints concerning the AXIS shafts. # 1 being the shaft cracking immediately behind the rear of the insert when using practice blades that are not sharp. Apparently, the thinner wall of the shaft can not handle the abrupt impact even with layered targets. That leads me to belive that the AXIS shaft could fail upon contact with heavy bone.

With these weight tubes, you can increase the weight of your finished arrow to meet the minimum weight requirements. A couple of benefits of the weight increase are increased penetration and a quieter shot.

Again, keep in mind the spine strength of the shaft and keep the FOC up in the 10 to 12 % range for your draw weight. You can also get different inserts that will increase overall arrow weight and allow you to fine tune the FOC of your arrow. The solid brass inserts from 3 Rivers will fit Carbon Express, GoldTip, Vapors and AXIS. The 50 grain inserts bump up from the standard 20 - 30 grain factory inserts. The only brass insert for the AXIS shafts are 100 grain.

There are also brass washer weights available to add 5 grains behind the broadhead.

Thus increasing the weight at the front of the shaft still requires attention to spine.

All of this is much alike to developing a handload for a sweet shooting rifle. It may take some time and experimenting, but the end result is well the effort.

Hope this helps...
