I've been rewicking up a storm today.
Tried a couple of spaced micro coils first, loaded up the lemon bar (from Terry) and Get Razzled. I wasn't really impressed. So not knowing whether it was the juice or the new coils - I ripped them apart again

Both juices tasted really muted, like going back to a Nova on silica wick. I could taste the Raspberry and the Lemon, but nothing special at all.
Anyway, scrapped those 2 builds and decided to try something different again - I know glutton for punishment
Been seeing a lot of talk about 3mm coils with rayon, so took some 26g kanthal and rewicked the RM2, 3 Kayfuns and 2 Russians. An absolute pain to get the coil legs trapped under the screws with 26g kanthal, but managed in the end.
Mixed some of the new MBV coffee that I got today with some of Terry's sweet cream. Did a 75% coffee/25% cream mix. Had about a quarter of bottle of Snickerdoodle left in the Reo, so I just added the coffee mix to that. Absolutely lovely. I reckon the coffee mix on it's own will be even better, but still an amazing vape.
Filled up the other toppers with Blue Moo, Grappler, Betelguese, LMP and the last of my DIY berry blast.
Using the thicker gauge wire and 3mm coils with rayon -
WOW
Blue moo tastes creamier and bluer

Betelguese, even more complex and fruitier. LMP has taken on a new depth and Berry Blast seems like it's got 17 flavours in now, rather than 7

The only let down is Grappler, I can taste the grape, but it's a real sort of fake candy and bubble gum flavour - not too impressed so far.
------------------------------------------------
Did all the coils at around the 1.0 - 1.2 ohm mark. 7 or 8 wraps, very tightly wound with the 26g kanthal. I've got more surface area with the coils, so there's more rayon in there - so far, I like them 100% better than my 2mm coils - huge improvement. Plus I think the coils will last longer before a dry burn, another bonus
