We've played around with wake foiling over last few seasons, mostly as training for surf foiling. I figure one hour behind boat is about 10 hours in surfing time, can really accelerate the learning curve. So with that in mind, we've been using smaller foils, aimed at bigger faster waves, and this has meant needing more wake. So we've tended to ride the wake right by the boat (18ft Campion with outboard). I made a wakeshaper with a suction cup glass carrier and wood scraps, that helps a bit ... link below to what I mean. Just $30 in parts vs $399
Goal upcoming will be to use the bigger foils and ride the 2nd wake instead -- as you say, clean unbroken wave. But also safety: I had the realization that riding the wake near the boat with an outboard is just too dangerous. We had a couple times where driver had an unexpected speed drop, and you accelerate into the boat so fast it's scary ... was able to turn away and pass the boat, but if not on it or an inexperience rider, you'd be into the prop in 1.5 seconds = death. That's a bad end to an otherwise fun play day.
Other thing is the rope. We'd have about 30 feet out and then pull up to the wake, holding the loops until ready to let go. We brought a wakesurfer aboard and they were sketched -- if you catch your leg or arms in the loops or handle, can be serious injury. Or catch the handle in board on a wipeout, potentially break the foil. They said what they use is a rope with no handle, with padded grab areas (floats) every 6 feet or so, you let it drag behind the boat (don't pull it in) as you can surf over it, but also if you lose speed you can potentially steer back to it and grab it without losing the boat. We haven't done it yet, but makes sense.
