What are you all thinking of - a curb strap or a lip strap are for use on curb or pelham bits. If you are pulling the bit through your horses mouth then YOU need re-training.
Abut 80% of campdrafters use lip straps on snaffle bits. About 60% of people who show Australian Stock Horses use lipstraps on saffle bits. They are very accomplished riders and trainers, and they DO NOT use them for no reason. The fact they are allowed and accepted tack at official ASh shows says something, don't you think?
In high speed, high adrenalin horse sports such as campdrafting, polocrosse, sporting and working ASH classes fast and sharp direction changes at high speed are ALWAYS required. The lip strap helps disperse some of the pressure and stops the bit from becoming uneven in the mouth, or 'pulling through'. This does NOT mean the rider needs more training.
