Quick Condenser Q

[lacedspirits]

I'm putting together a 2" Compound (Boka-style) Still. I was planning on using 3/8 tubing for the top condenser coil but after drawing it out I can tell that I'll only be able to fit a single 3/8 coil, not a double. I have figured out that a double coil is possible to make using 3/8 for the outer coil and 1/4 for the inner coil, and just connect them with a flair fitting (H2O in 3/8 and out 1/4) Or maybe making one 3/8 outer coil and just soldiering a plate in the center of the coil half way up and another further towards the top to direct the vapor towards the coil. I used to do alot of plumbing work so I have tons of fittings and around 50 feet of 3/8 and 1/4 tubing so supplies aren't an issue. I've been running this through my head for almost a week now and am getting to the point where I'm wondering if I'm over-thinking it and maybe I should just throw the 3/8-1/4 double coil together and just see if it works.
Any insight would be greatly appreciated.
Thanks in advance,
