Hey mate, yes I had another play with cotton (rolled) in my RSST, U-wick, micro coil, cotton birdhouse and all, still a major fail.Cotton balls are the same as the rolled cotton, if 100% and sterile, and no other nasties added. I get that bloat too with cotton balls and gennys, it just does not like being vertical. The pads I have are 100% cotton, but they have been heat treated and compressed on the outside and are puffy on the inside. While they initially have good structure and stay in place in gennys, they eventually bloat up and go to cotton heaven just like the other stuff. (for me at least)
However in my Octopus dripper, a 0.9Ohm tooth pick/cocktail stick sized micro/mini coil is going great.
The RSST is now back to the 1 Ohm 6wrap tooth pick/cocktail stick sized micro/mini coil on unoxidised #200 U-wick and going great, good flavor very fast response and great vapor all comparable to my 0.7 Ohm previos setups at least so far.
I always wonder with these set-ups what folks are accepting as satisfactory vapor and flavor production, I think I am a demanding vaper and will find the weakness in any wick coil set-up very quickly, my mech mods are all tuned to very low voltage drop, and my coils are always sub Ohm. The ceramic 60 grit white Al/Ox you put me onto was ok( insert: geat for medium wattage vaper), but still only ok. I was using 32g kanthal double parralel coils ( run like twisted, without being twisted), and that enabled a good contact with the wick plus good heat distribustion, plus easy wrapping and low resistance, I settled on a 2.8mm wick with 3 dual wraps comming in around 0.8-0.9 Ohms in the DID std. Like I said ok, but cannot compete with un ox #200 Uey at high wattage.
It will be interesting to see how the vape on the Ithaka holds up wih the varios setups and wick materials I am planning to trial in it.
Did I hear you have become a Reonaught convertor?
