Dr Deb Bennett

Very interesting site and forum from a very knowledgeable lady. She doesn't overtly promote bitless but acknowledges that the horse can be trained/collected etc perfectly well without one

Useful reading - the paper on true collection - interesting that she calls the bitless jaquima a 'snaffle equivalent' (take note dressage establishments )

Also an interesting thread on the forum about sidepulls

What a fascinating article on collection! It should be compulsory reading for all riders! Its inspires me and sees me through my self-doubt when people hint that my 5.y.o. should already be 'working in an outline' when she can barely do a 20m circle in trot yet, without falling over herself!
