Multiple Cold Finger

[arizona moon]

I've been playing with a multiple cold-finger arrangement for a reflux condensor and wanted to get some opinions. I started this because I thought it might be easier to clean than a double-coil and perhaps I could get better heat transfer due to the even spacing. The surface area for 7ea 8" long tubes totals about 89 in^2.
I forgot to draw endcaps on each of the .5" tubes. Sorry for the drawing quality, I'm not a very good draftsman.
I'd need to put a notch, spacer, or hole in the cap or column to act as a vent. There's a bit of soldering involved, but the design seems like it might work ok in an inline still like the Bokakob Mini.

Here's a rough drawing:
