aps2 ex 3 element piston on high pressure piston?

[Bulb]

Hey folks any advice or info very much appreciated as im a bit stumped and now sure which would be the best option to get this bad boy firing its best.

Currently the aps2 contains:
pss2 aero chamber with soft hop and 6.01 barrel
pss2 barrel spacers
pss2 zero trigger (red type)
pss2 teflon cylinder
pss2 power accuracy cup
pss2 3 element piston
pss2 bearing spring guide

I think thats everything. What im wondering is if anyone can tell me if im better sticking with the 3 element piston or going for the pss2 high pressure piston for better performance. Also if someone could give me some kind of an idea what the pros and cons of each are that would also be great.

Thanks in advance.

I cant really answer the question but im using the 3 element piston in my M24 with similar upgrades as above and cant fault it? Quite consistent fps readings around the 480fps mark and good gun performance all round

I had prety much all those but no bearing on the spring guide, had a pdi piston that was in three parts and the airseal it provided was excellent, verry easy to cock.

Only thing i would do is replace the barrel for a 6.03/4 for better results.
