2 plate pot still build question.

I guess this belongs in this category....

So I recently did some work building a cooled pot still riser for a 5 gallon milk can boiler. The original intent was not to build a functional reflux column but as it played out that's pretty much what I ended up with. The riser itself isn't terribly long, 15"x1" id section about half of which is an outer coil dephlegmator. Above that is a 4"x3/4" id section intersected by two internal cross condensers which then connects up to a 20 inch lyne arm ending in a 20"x3/4" liebig. It accepts reasonably firm packing filling about 14" of the 1" id section with ss scrubbers. It uses a needle valve regulated cm style condensing system and gives about a plate to the still at reasonably high energy input without horrible flooding issues (it happened a little at the med/high to high power but not too bad) which surprised me. I suppose I just have to run a notch slower, it gets huffy at higher power as well. Anyway, so I have this odd, modular reflux riser I can slap on top of my 5 gallon boiler. My question regarding the use of this thing is quite simple: is it best suited simply to use for doing my spirit runs and do my strips the normal way? I'm willing to bet I could get good performance out of it at the lower energy input of spirit runs but I guess I want a second opinion....
I've been running glass stills for over 20 years now and have no shame in saying so.
