Pot still question

[Maestro]

I have built a pot still and run a few washes through. In the process, I am beginning to wonder how I could improve.

First, I think my column is too tall, 36". I think I am heaving to run harder than I should and smearing quite a bit. My lyne arm is pretty long, too. I think there is some parasitic heat loss.

I will try to post a pic and see what input I can get to improve the final product. For the record, I am fairly comfortable with working.g with copper and me end goal would be a still that is well suited for whiskey/rum with the occasional neutral.

FYI, the pic is a cleaning run. The plastic funnel is not involved in collection.
