Justsomeguy? and now ubertuber? You're hard to keep track of, my good man. Certainly "fun" is always relative as is a "challenge". No argument. I think the single best small wave surfer in existence is Rob Machado, the way that he described getting that way was riding on days others stayed home, because the surf was flat. IMO, many folks build a large wake rather than working on their skill set, first. Strictly MO, with a great foundation in your skills, the size of the wake is secondary both in having fun and being challenged.
