I believe the airflow control is decent and will allow MTL closed most of the way.I know @Christos - it was very close.
My only concern now is that I left out the smallest air disk.
I got all the others because I didn't know how this thing is going to turn out - so better be safe than sorry.
Now I am worried I left out the tiniest one - just in case somehow this tank becomes a mouth to lung winner.
I know Rob is at the Wild Coast - maybe if @Takie sees this message he can include the smallest air disk for me. I will sleep better...
Lol
I got the biggest airflow option with no other air disks. The options are IMHO too much and debilitating when trying to make a choice.
Also I think you will see some disks in the classifieds after this group buy. The disks are 6 euro and the sheet says +- R56.
I think it's R84 if it's 6x R14.
Either way I'm sure I'll be happy with the skyline.
