Just bought a new blitz and I'm loving it. Took a few times at the range getting use to it, and now it runs SMOOTH. 0 chops. Definitely needs a decent hopper. Absolutely run HPA. Easy to change the barrel down the road, lots of options unlike the spyder which IMO, built with less quality and care.
Azodin customer service is mind blowing.
I say for now Azodin is the bang for your buck gun.
