I converted my IGO-L's and Phoenix V4's by removing the center pin, filing 2 small grooves into the insulator for the juice to flow to and from the deck, then reassembling. It takes less than 5 minutes each. They work great! There is a thread around here somewhere showing the process. Good Luck! The Reomizers from Reosmods are fantastic if you decide to try one.
You may as well go ahead and pick out Reo #2...ask me how I know lol.
I'm thinking about the "slot" method because I could use my Dremel with the diamond blade. Does that method work as well as the center pin hole?
