PMR for sure, i use to own one and it was great, it can also take more upgrade parts such as new bolts/rammers and it has a larger variety of upgradeble boards.
at the moment all you can get to upgrade on the SLG is the trigger, back of the rammer thing, the eyes, and the choice of one board.
the PMR has all that, plus the choice of more triggers, more board choices and also new bolts/rammers (you can find al these on nextag shopping search lol).
The PMR i found was also much more acurate than the SLG and could carry a shot further with still a good accuracy. and for 30 pound more why would you not choose it over an SLG lol.
