Mike H is still my top TT rider, should have won 4 in 1961.
Watched him on the Honda 4s/6s, so fast and smooth.
Won on Suzuki 2 stroke, Ducati twin, Norton single, Honda and MV multis, mainly against the best in the world GP riders [How would the current riders fare against Marques, Ross, Lorrenso, if they took up road racing? ]
Joey will always be the best road racer ever in my mind, but Hizzy the best TT racer.

However, if MD retired at the end of this year he would still go down as one of the greatest TT/road racers ever, I am always astounded when ever I watch him.
If he does continue, then he could become the greatest, the number of wins does not tell it all, were they leading and by how much when they broke down and who were their opposition?
