Piston Question

[etd]

Pretty simple - upgrading my upper mechbox and I wanted some input.

I plan on eventually turn my sig into a lipo ready gun (don't comment on why thats not a good idea please).

Just wanted to know the best piston for the job. I was thinking either Systema Aluminum Piston or Prometheus Hard Piston, I plan on upgrading my gears in the future to use a high torque setup with full teeth.

Get the prommy, its not a good idea to have hard teath on the full piston one ar two metal teath is all you need. Get some good gears (and metal bushings) as well, they take more from lipos. The nozzle, cylinder head and spring guide need upgrading as well, V3 for the sig don't forget. If you want a high fps invest in the sorbo cylinder head and piston head to save the mechbox some wear. I don't know if you need to swap out the motor, if it can't pull the spring it will be a problom but with lipos the rof will go up and you should see all round motor improvements (moe wear though).
But do yourself a favor and read up as much as you can on this cuz you don't wanna waist money.

one positive thing about the metal piston: if your bearbox is badly mounted, if it's meant to go wrong, sometimes you'll break both piston and gears.With a metal piston you reduce the cost to 'just' new gears

On the counter to this, your gears are less likely to strip with a completely (or mostly) poly piston :P. And then all you'd have to do is replace the piston.
