You got me looking, and here is the DrJones post. If the two sided Nanjg 105C is too tall, then my driver is going to be too tall also? The inductor height is going to be 2.8mm, plus 1.6mm for the board, plus next to nothing for the resistors. Otherwise, I like the looks, and the side switch of the T2. Also took a peek at the T2 review and teardown on BLF.
A P60 seems more universally upgradeable.
