PTFE ball now up and running , and wow , that is all i can say , i have sent some madmoon , vintageaxman , and a couple of others i have some spare ones if any one wants to try this , NO harm has been
done to any TT during the little tweaks , and every Tweak can be returned to factory spec ,if you dont like them but i would reccomend the ZX1 extra lube and the PTFE ball ,
