I've asked my self this question many times over the last few weeks and I've asked many others and it's quite close to what I can gather but I have gone for the rota
im sticking with the rotor,got a dm12 needs fixing then i can start looking again il get both and see which one i prefer thanks! im running with a luxe
the spire is quite good because of looks however sometimes when you put paint in it still spins around as if you had no paint inside, however the rotor jams alot with crap paint especially so just get a z2
I like both.
I prefer the mechanical rip on the rotor to the button you push on the spire.
I've had both, went back to the rotor.
You'll find people on both sides of the fence on this one so...
Get the new HK loader
Jk they all do the job well
