All of them. hoppers have a standard feed neck size and the azodin neck is adjustable.
If the back is auto-cocker threaded, then yes.
Yes, a halo hopper can fit on most guns. If it doesn't fit at first, take sandpaper and sand the feedneck down.
The Pinokio hopper is the only hopper that holds that many paintballs.
It would depend on your budget. You can only shoot as fast as your hopper. If you have say 200 dollars, you could buy a SP vibe, Automag, Alpha Black Carver or Azodin blitz and spend the 30-50 on an electric hopper.
Since the blitz has eyes, it can shoot fairly well with cheap 30 dollar hoppers. If you want something that will keep up with almost every gun, buy the Invert Halo Too for $60
From the pictures it doesn't look like you would need an elbow at all. The hopper should fit directly into the feed neck.
Yes.
yeah
No, the mounting screws are different, it will not fit the 98. There is a 98/USarmy cyclone feed made that will fit.
15.

Firstly, the Blitz is built on the koas model, plus an adjustable blade trigger, ramping (near fully automatic) board, eyes, regulator, macroline system and is the "middle grade" in the Azodin line. The kaos and GTI are entry level markers, and the Blitz was designed as a mid level gun, so there is really no fair comparison. In addition Piranha gti is a relatively old, and in general low quality gun compared to the entire Azodin line.
