Grappling Clinches usually do not favor the taller guy. if you ever get into Muay Thai the height will be handy there.
Some stuff will be handy for you tho like if you look up the "Power Twist GrecoRoman" that should wind up being a good takedown for you from the clinch as a tall fellow

of course you might not ever want to compete or anything I'm just throwing out ideas as I tend to do heh
