Unfit horses lather a great deal more than a fit in condition horse. It's a fact.
It is not unusual to lope a cutting horse hours at a time. You won't see a speck of lather on them. They will be wet with sweat, but no lather.
We are talking rein contact with the horse, not the rider.
Please remember a cutter doesn't work the herd for hours at a time. You work a 2-3 head and then typically the horse gets a break.
When you lope out horse that stays in frame, where is the contact? Reins are draped, you lope left, and then you lope right.
But it doesn't matter the discipline, horses lather with contact. It's a physics and chemistry.
