I'm thinking about replacing the ceramic & holder on my 2 Odys with the new Ithaka dual coil. I like the shorter center post from the Ody with the positive nut, and the 510 base. I want to use the new Ithaka (inside) ceramic nut. This my thought replace the tanks, caps, mouth pieces, and ceramics and holders.
It looks like the grounding neck on the Ithaka ceramic holder will have to be cut off, and it should be a direct replacement.
I Havant had the time to see if the new style inside ceramic nut will fit the original Ody pos post, I'm hoping it will.
The cost to upgrade one is right at $100 per Ody.
