The ultra has superleather(man made synthetic) and the elite is Cordovan. Both are nice and have the same geometry and plate size. The elite is metal plated and the ultra is some sort of composite.
I like the Elite better, as it gets a bit cleaner release for ME. What I did was buy one of each and then keep the ultra in my pack as a backup and also switch it out and use the Ultra as number one durring rain or snow.
Dennis at Git-r-done (Tradgang Sponser in the dropdown column) has the best prices on both models I have seen.
Both of them are the best tabs I have ever shot.
