Do bigger wider columns lower yield vs more narrow columns? Say a 3" colum vs a 8" wide colum?

That was my experience open blasting - I cant find any info regarding this. If anyone has any links/experience with this post here please.

I was thinking of using a shower head then reducers at the bottom the create back pressure. Thoughts?

We got higher efficiency with smaller diameter columns when flooding from the top only. About an inch diameter was highest, and smaller was too hard to load/unload.

Less of a difference bottom flooding, and we used a shower head at the top of our 4" columns for kif.
