Some "saddle maker" says the difference between in-skirt and tree rigging is...."..in-skirt is supposed to be more secure, and the latigo rigged directly to the tree allows a bit more freedom of movement..."
Wow I learned a lot from that!!?? I'm not sure who or what gets more freedom of movement from a tree rigging?
The fact is, there is no definitive answer as to which rigging is correct. There are too many variables and each situation has to be evaluated separately.
Variables include the style of saddle, shape of the horse [not condition.. body shape], proper fitting criteria and discipline [i.e. what works for the discipline, not necessarily related to proper fitting practices].
I can advise what is best if I build you a saddle.....what you choose, you will have to live with!
Many thanks to all who post "stupid quotes" on the net. Keep them coming!!!
