That is not that simple bro...
Favorite - I have many, but if I have to pick 1...
Erich Schmaltz - If you saw him ride, if you knew his story, if you heard his message or if you truly knew his impact on the sport of wakeboarding and skating as it is today... You would realize that despite the "corpo industry opinion" of the last 5-10 years, he pushed "opinion" aside and forged the trail of the "FREERIDE movement" that is recognized by riders that continue to push the envelope of creativity. Pro's as we know them would NOT be the cast of iconns that they are now without his selfless passion for evolvement. We as riders all are indebted to his preserverance (sp?).
MOST POPULAR RIDER -
Parks Bonifay TIED w/ SHAUN MURRAY - Why because they are THE POSTERCHILDren of the sport as "Joe Customer" knows it. Both are innovative riders, both rule ad driven popularity, both will be legendary.
And that's not beating around the political bush...
