Got 5 dicodes tubes and 1 No6 box....they are absolutely fabulous......if you go the Dicodes tube route make sure you get the V2+ , I would buy the S, as they can be extended also to 18500 and 18650 format with optional tube extensions, while the M can only be extended to 18650 and the L version is plain old 18650, so the S gives you more flexibility.
Best tubes out there!
