Nope, the HALO A didn't have the spring, it wasn't a true force feed system. The HALO B, however, is and it causes problems with the IR3's (balls don't roll FORWARD past the detent, they roll BACKWARD past the detent, and get stuck behind the COPS rod so that when you shoot there is ball behind the COPS rod, and another ball half loaded, and you break both of them). I'm not aware of any problems with the LCD's, from what I've heard they work fine. I have a HALO B on my IR3 that works great, I just put a stronger ball detent in, and it fixed all my problems. The new TE software is supposed to clear up most Angel problems anyway.
