Rotors are great very durable very efficient and is quick but the Spire is defiantly a contender just grab the upgraded ramp and and a virtue crown it will run like a dream just a little more pricey than the Rotor, yet alot more low profile
I now have both Rotor and Spire and they are both great.
I sway more for the spire as I find it better for some reason but either of them are great to have and I love the high cap and 260 shell for holding more paint.
Because the roter is made out of a better materiel than the spire and is much more low profile and when you buy products from dye you know your getting top quality
