I've researched some, and I've decided that I want an actual horsehair mecate for the traditional aspect. Also, I have a mustang, and I thought that the traditional look would be best on her. I'm getting a Guitron bosal, so I might get a Guitron mecate, but I was also considering a Jose Ortiz or any others that are suggested here.
I use a yaght rope mecate. I like them better than horse hair. Horsehair mecates require a lot of special care and come in two kinds expensive and crappy. Sometimes the crappy ones are expensive also but they are still crappy.
