I do all kind of kiting: speed, snow kiting (on ice/mountains) TT, long trips, boosting, hf (strapless, no boosting), usually it is just cruising around. I've reached some 30 feet from the flat on TT and for sure I could get higher in high winds or using ramps but locally there is not often such conditions. I'm also not that young any more and I've had some injuries so I leave Woo record chasing to younger people
Of course I understand what some hf users want from single skin kites, I know that kite type well. Personally I just don't see it that important or worth risks of failed relaunch. Gin Marabou is obviously a step forward in that respect.
It is a fact not everyone needs high performance (high L/D) for their kiting. For a designer perspective low performance kite (which quite easily comes with good stability and drift) is not that interesting because it makes quite a lot achieved development unnecessary. Kite like CA Wave could have been made 15 years ago: low aspect low cell count kite with a simple bridle. Ok, Wave has span wise straps and LE stiffeners but there is not much to design in them. Using lighter weight fabrics is trivial like it is to constantly measure kite weights and make conclusions from some minor differences.
