Really guys? These are your suggestions?
Budo and elbow, seriously you don't have enough information to be given that advice. Sang is right; need video and more information to lend advice. I'm used to fighting tall fighters. Been doing it most of my pro career. There is no 100% way of doing it without knowing more about the other fighter.
Orthodox, southpaw or switch (doubtful switch fighter)?
The advice given to you is based of cuing off the front leg. If he's assuming the stance I think he's using you need to switch to a modified side stance and work his inside.
