When I went from drop-in coils to RDAs I got lots of experience with wicking. Making the coils was super easy for me. I have coil jigs that really helped me starting out. Wicking was my downfall, I didn't drip often enough and continued to get dry hits. I really had a problem with dripping. When I finally got my first RTA I was in love. The experience I learned on RDAs paid off with the use of the RTAs. Nowadays, I just use a 2.5mm machine screw to make my .5Ω SS316L spaced coils and the Coil Master TAB 521 as a build base. Oh, I also found using a small electric drill to twist my wire prior to making the coils stiffens the wire making it less springy. I keep the twisted wire in a plastic straw in my coil making box. I highly recommend it.

I can't get used to dripping well i keep forgetting to drip and have had quite a few more dry hits recently, overall my wicking isn't bad, mainly because i use the Vapefly Firebolt Cotton that @nwhornet told me about. I seem better with squonking which i guess is the same as dripping but feeding from the bottom. I would rather stick with RDA's though instead of RTA's, mind you there is nothing wrong with using both i suppose. Would like to get the Wotofo Unity but read it's difficult to build on so might wait a while.
