Wow!! I love vape-mail from Greece... Especially today with the latest design ProVari extension & ring from Kir Fanis.
Provari extension-cap+ring - Gr-Modders
The ring fits tightly with my Hercules.. Can't even turn it if I want to. The extension base.. Well, again... WOW! The only PITA was removing the spring from my stock cap, and installing it in the new one. I would like to see future extensions come with a spring already installed. The bottom ring with holes does not come off, and it's somewhat difficult to get the spring seated inside the deep tube. I am fortunate to have a beading tool kit with a long set of tweezers which helped greatly. It was worth the effort though The set also comes in brass.
