Matt, I've gone on Saturdays but as the weather gets cooler there'll be less people using it and it'll be less likely that I'd have to do a rotation. I have my drysuit out getting new seals so I'll be going year around. Late afternoons are good too though.
DC, there is a size restriction (21' I think) but no weight restriction that I recall. The shore is concrete so erosion isn't an issue. That said, I don't overdo it but the wake is plenty ample..15' in to the flats isn't an option nor do I care to do it. 75' rope w2w's are my preference. I was over at Crystal today (didn't board), looks like most of those boats are ski boats, not sure about their restrictions.
