Nobody can tell you the shaft you need. Only you can. Matt showed me some nifty setups with goldtips where you can add weight to the front or back depending on what you need.

First off I suggest you get out in the yard and start trying to get proficient at hitting a recongizable POI or group. That may take months. In that time taking about 30% of your time working on your release, anchor and form.

I like bareshaft/broadhead tuning at this point. And this can change over time, in other words, 2016's at 30" used to be perfect for me when I first started. As my release got crisper, form nailed, down, I now require 2018's with 125gr points or 2020's with 145's. The 2016's are too weak.

I bought several points from 125gr to 250gr just for this experimentation.

But if you go the gold tip traditional route, you can add wieght to your front or rear. And then when you find the spine/tip/BH combo, you can add equal wieght to the front and back for heavier setup for hunting, or take off equal weight tip/nock for 3d.

It sounds very nifty, but can't bring myself to go the carbon route.
