There is one distillery i know of that keeps running heads and tails in their washes as their theory is that heads and tails compounds clump together and concentrate in the run so you are always taking the same sized heads and tails cuts.
By increasing the concentration of the heads and tails they boil at lower and higher temps (respectively).
Altho most people with a bubbler only ever bother with a feints run, feints of feints you toss the tails and keep the heads as cleaner.
