are you talking about that thumper tower column you built?
I unfortunately can't look up individuals builds, only posts and you have a fair few so searching through all of them to find all of your builds is a little onerous.
If you are talking about the thumper column then wouldn't the thumper and 4 inch plate section make the world of difference to a straight 2 inch column?
Also and please don't read this as if I'm being an arse but generality is pretty much how this thread is based, as in general the findings for 2 inch plated columns aren't favourable however there are exceptions. Also as USGE said (paraphrasing) a 2 inch plated column can produce decent distillate but there is no real improvement over speed of a normal packed 2 inch Boka.
Of course usge did point out that abv of wash and size of boiler supplying the column does play a role.
It was merely my point (somewhat off topic) that unless you absolutely haven't got the space then the pain of a small diameter column isn't worth the money saved, in fact running time and power/gas used would probably eat any savings made.
