Silicon hose did the trick for me pushing ttech for a 6 hour session and the pusher stayed put the whole tattoo... The new version of the Centri addressed all the problems of the first version for sure.
My first complaint with the gen 1 machine was the stroke was hard to adjust and kinda irregular... The new version is easy to adjust and holds its stroke nice and consitant.
Second complaint of the gen 1 was it's size. The new machine is smaller and less bulky, feels like a normal machine not a brick.
Third complaint was the connection placement. The new swivel Rca is amazing... The cord never feels in your way.

Overall this Is a great machine it lines pretty well, but it's biggest strong point for me is color saturation and blend stuff. It's definitely fun to tattoo with.
