Feints -- when and how

[Mr_Beer]

This post has some questions regarding Feints - may be obvious to everyone but I still have questions…

I scoured the forum and came up with two posts that seem to answer most questions…

I have a pot still and am focused on flavor. At this time neutrals are of little interest.

My Understanding and Associated Questions
Feints are a collection of heads and tails that did not pass muster from prior spirit runs as best as I can tell. The idea is to not discard, just put in the Feints jar for the future. Is that true?

Mixing feints from multiple types of prior runs will result in a hodgepodge of stuff.
An all feints run of a ‘hodgepodge’ of material may have a good flavor or something unusual. Experimentation will tell. Opinions??

Continually reusing feints over multiple runs will result in a concentration of the off-flavors that caused them to be reserved in the first place. Use once and then probably discard or only save the new batch tails. Opinions??

For flavor purposes, the tails may have the best results flavor but the lowest drinkable yield. Opinions??

Feint runs from ‘all feints’ stock may be less flavorful than mixing the feints with new beer to blend in flavors? Opinions??

Feints are typically only used in the spirit run – is that the consensus??
