i know some guys like em....as far as pipe and header combo i pretty much tried em all.....i had the best luck with the ofna 063 pipe....the motors were very durable.....and your right they asre very picky motors.......i run medial pro jp mod motors now...and also a v spec.....the medial pro motors are deff over powered for most technical tracks and the v spec well the v pec just runs good...i never have any issues with the v spec or my medial pro's they all 3 hold a tune very well......
