thx, but i hve one. he came to me in a normal dutch gag, which after being recommended a universal, i sold it. after weeks of no probs, i then got tanked off with in the universal, twice. so bought another gag which happened to be a hollow mouth. he still tries it on, so jst wondered if the lightness of the bit would make any difference to control. but if kinder, i'm happier. hate the gag, but if thats what suits him, i'll hve to put up with it.
