For me, being the MacDev fan I am, this was a hard decision to make as well. Unlike some of the other posters, I actually like the feel of the axe in my hand. The grips are amazing, the front milling fits well, no macroline and an extremely simple toolless bolt removal. Add a lurker eigenbolt and you have a gun that is smoother than most $1300+ spools and is capable of pinching paint. Factor in the fact that parts for axes are friggen everywhere and are dirt cheap and it makes it an even tougher decision.
Stock vs Stock, I believe the drone wins every time. When cost and features are factored in you've got an even harder decision to make, add a boss/ lurker bolt and it's a coin toss.
Have a NDZ or Tech T axe bolt you'd like to trade for Boss bolt or sell? PM me!
Donations for an ultimate bolt test would be nice too.
