Anyone know what the diameter is of the twisp edge? I know it has a 510 size mouthpiece so I am wondering whether its mouthpiece will fit (neatly, without overhang) on my AIO D22 XL. Man I miss that mouthpiece , I have a flat drip tip at the moment but it's much longer and just not the same. I only MTL so a flat drip tip makes quite a big difference to me
