50/50 mix will take a little longer to wick in clearos, means you'll have to wait a few seconds/minutes if you're a chain vaper off and on or tilt the clearo upside down more often to keep it wet.
I have a LT. It limits the voltage on LR cartos to 2.5 volts output but it will work with anything from 1.25 DC to 3.0 SINGLE coil cartos or clearos. I like the LR because the vape is hotter and don't care if I get a voltage limit as long as it works. I now have a Provari and with 1.25 ohm cartos, it won't let me go past 3.8 volts before throwing an error to protect the carto (similar to the LT, it doesn't give you an error, it just kicks down your voltage without telling you........) As far as wicks, some like the shorter wicks, I prefer long wicks, they seem to wick better for me but I mostly use a
tank setup.
