Using Lemo with nickel on a IPV4 for TC now, no wicking problems at all with the tails of the Japanese cotton right above the deck, flavor is great. No leaking to speak of unless I shoot too much
juice in.

Flavor is great. Draw is a bit tight with the air flow screwed all the way out.
Lemo 2 is being used with a 22ga Kanthal build .4ohm on a Sigeli 150w running at 55w currently, thicker juice than on the Lemo, lots of air flow if I want it, less if I don't. Gotta love a properly adjustable tank. I may wipe up a drop or two after filling, but no leaks there either. wicking the same as the Lemo. If I close the AFC to about 1/4, it draws like the Lemo, but I usually have it at 1/2.
Will be comparing with a Billow v2 tomorrow, but then we are back in dual coil land.
