2" vs 3" Column for VM still

[Drosteo]

Hi,

have been readin through multiple posts in this fantastic forum and have decided that i would be best to build a VM still.

Was wanting to know the pros and cons of going for 3" vs the 2" that most people tend to use for their column.

Also if anyone has any good plans for a VM still i would definitely appreciate a PM.

Thanks in advance
