I belive that's your best bet, get a higher power gun and tune her down to where you want her,...I would say Hatsans with the SAS are the best candidates for your project
So the 34 is an 18 FPE gun ?I would swear the Nitro Venom definatly shoots harder, very definatly smoother and easier to cock I have a Vortek kit for my 34 but haven't installed it yet
