Best WA/GP/Prime Nozzle/bolt/buffer Spring Setup
						
						
																											Which bolt/nozzle/buffer spring combination is best for game (good kick, speed & won't slow down too quick)?
I have tried: 
1.RA-Tech NPAS nozzle + RA-Tech Steel bolt + Shooter 90% spring: OK.  Kick is ok, speed ok, but eat too much gas (Slow down quick)
2.RA-Tech NPAS + airsoft surgeon VLT aluminum bolt + original G&P Spring:  SLOW, no kick
3.G&P nozzle + airsoft surgeon VLT aluminum bolt + original G&P Spring:  OK.  Kick is very light
4.G&P nozzle + G&P original bolt + original G&P spring:  Best.  Good kick, speed & reliable.
Conclusion:  Airsoft surgeon VLT aluminum bolt too light, RA-Tech bolt too heavy.
Anyone have better combination?
