Angel AIR system, but that system is so pickey that you will go crazy. You cannot fill it if you already have air in the tank or else it blows a disc, then you have to replace it. Plus the AIR system is not as consistent.

-long drop foward
Totally reliable as far as consistency of pressure goes.
If you think it has a weakness you havn't used this system
Basically for those of you who have either gone mad using other air systems or are looking for a reliable air system this is the ultimate deal. Sure, it is a little more expensive than other systems but their new retail price (I discovered it at a local retailer) will make it totally affordable at about $230!!! Quite the bargain! Anyways, this system can be fine tuned to your gun to only vary 1-2 degress. When I tested mine the cronograph would only bounce from 299-300-301 fps. So no matter what your reliability is great. Plus the regulator on it is great!!! Plus the tank is reletively light compared to some systems!!! If the valvue seal leaks all you have to do is take a quarter, unscrew the plate, and flip the piece over and WHAM, it's fixed!!!
Jumpin Gehosophat Gehad. (don't ask) basically, I am never going to consider buying another air system, ever.
