KTM, would you remind me please as to what it was/is that you don't like about the 510 on the Nano?
The 510 plate is the ground and not very solid being screwed on and you can't tighten it too much because of the c-frame design. A solid ground is very important for TP.
I also have issues with it unscrewing with my KF5 and KM3. I have other mods that are more reliable so I put it aside so I don't have to deal with it. I'm currently in love with my Silo mods. Even my Vaporsharks have taken a backseat to them.
