It occurred to me that folks with TWH and ASB might also be looking for wider bits. the link below is to a moderate curb bit with an adjustable width.

I would like to see one of those in person, seems like a good idea, but the proof is in getting hands on and playing with it.
For info this bit http://www.ridingwarehouse.com/Reinsman_Seven_S_Mullen_Bit_w__Independent_Shanks/descpage-RSSB.html measures a generous 5 1/4" toward a tight 5 1/2" I may be on the point of ordering it!
