Scott,
The E-MAG and PMAG if larger than regular Mags are minimally larger at
worst.  I have my original MAGs and will do a measurement the next time at
the airport.  I have the short engine mount on my 360 and had absolutely no
problem installing them with the advantage of no external units to deal
with.

"Scott,

1. P-Mag had no history, no experience and users that they could reference
(except for one aerobatic guy that had experience with one E-Mag).  There
was no hi compression experience.
2. They are big and I have no room.
