Re: i was thinking about this..
that would still be the same...if you lightened the striker but put a heavy main spring is almost the same as having a heavy striker and light spring., and don't cut another blowback port...just screw the SRP all the way out and just widen the gap on blowback port of the rocket valve a little, not too much or you lose fps. a med spring should work with a normal striker.
btw have you widened the port on the VA? that would really help your airflow issues if you haven't.
