I'm actually liking this bizarre configuration so far. The upside down drop puts the tank an a place that rests against my forearm making it easy to aim and steady at arms length. Should be a nice run & gun configuration. Plus it draws out the lines of the Angel frame and just "looks right" to me. The air line is not really working out where it is. Ideally I could pick up a reverse valve (or have this one tapped on the other side) and switch to a side ported ASA. The other problem I didn't foresee was the lack of a safety on this frame. Going to have to kajigger one up somehow. Any machinist (paid) volunteers?
