Actually, you are going to want to do a lot of the stuff on OtterSC Customs and shave the hammer.
It will lower the opperating pressure of the gun, give you more shots per tank, and resuce kick, so you will have a real beast!
I want to emphesise (sp?) on the lowering of the opperating pressure, as stock spyders need the psi to be a bit up there to work properly. With all those mods, my Spyder can work off of about 300 psi consistantly, much better than stock
