Rigging: what is this, and why does it matter.
Gullet: We have these on English saddles, but they only come in small, medium, and wide. On western saddles it seems as though they actually have measurements. I think I will need a 6 inch gullet for a high withered thoroughbred. Is that correct?
Bars: Ok someone told me these are what actually rests on the horse's back, and can be quarter, semi, or full. Again, dealing with a relatively narrow backed thoroughbred, do I need quarter bars?
PS: If anyone knows of a good saddle brand that can accommodate a thoroughbred, please let me know. I don't have a fortune to spend, and I like synthetic saddles because they are lightweight.
