03 vert cocker

If you plan on upgrading this much, just save some money and buy a higher end Cocker. It'll look better, have a higher resale, and you'll most likely be happier.

Agreed, if you don't know what you're doing (and by "know what you're doing" I don't mean "know how to time a gun" I mean seriously know what you're doing) then the best upgrade is nothing.

Otherwise, get a new 3-way (belsales), and simply respring the valve and hammer until the gun pinches and is more efficient (lightest hammer spring, second lightest valve spring usually), then get an adjustable lpr (or adjust the stock one but what a pain) until it's a little higher than the lowest pressure it'll reach. Then re-time the gun and cut the sear spring and trigger spring a little if you want a lighter pull. Add a new barrel and your gun will perform way better....no chops, higher rate of fire, less recoil, much more efficient, etc. and all for pretty cheap.
