Going old school. . . Bob Peoples, Mighty Atom, Saxon, Goerner, Warren Lincoln Travis all would be awesome. Getting instruction from Dan John and/or Pavel would be pretty cool. My mentor was a guy called Bill Clark. Coudn't have asked for a better mentor.
First and only person to have ever performed a zercher and steinborn lift over 400lbs in a single meet. Bad bench presser though. If I had the time I would like to meet and learn from Dennis Rogers. If I had a lot of time I would learn from a local strongman Steve Schmidt. Known to few. . . the guy is famous for pulling a 50,000 lb train with teeth and bending some outrageously large horseshoes. Good lifting!
