As said different strokes on the switches. I prefer the X's over the V3's, and the V2.1 over the V3's as well. Part of that might be because of the first V3 I got, a SS 18500 Edition with the old style ring that has sharp edges that bug me. Just a mind set thing carrying over to all V3's maybe that I haven't tried to correct yet. Part of it is also because I have so many PAPS now that I don't run them all at the same time... tend to use the favored ones most of the time and the others only ocassionaly. That'll change though when the 3 new drippers for the PAPS I ordered gets here as I'll dedicate 3 of them to the drippers, and probably in shorter configs. I just can't seem to get away from running all the X's in 18650 even though I bought an extra SS main body and switch with the intent of making a dedicated short config X. That switch runs the LUX 18650 tube instead.
Anyway, right now 3 X's/Herons and a MicroStick/Sofia are on line, and one of my VV3's with a palate cleanser liquid. The Ti will get thoroughly cleaned today, probably get a SnP SS tank/Sofia for it's maiden voyage, and for pictures. Want to see if it feels top heavy with the tank, and to get some use with some of my Sofia's that have mostly been ignored ever since all the Herons (and the Spheroid) came to live with me.
