Funny I was going to use the same expression. I can't deny that this kite it seems will indeed force you to learn to trim correctly and could very well give you a closer experience to true sailing.
Personally I'd rather concentrate on what's happening underneath the wing with my body and board, not the kite.
Been experimenting quite a bit with low and high Y setups lately and indeed trimming right, especially when unhooking is important no doubt.
But you don't need a cloud to teach you this, that's for sure.
You want a cloud for other reasons, lightweight, drift, low end per kite size, small pack down size for traveling, quick to pump up for those guys that are time poor, etc etc
I would not putting it's sensitivity to fluttering given a set bar throw on my list of priorities for kite, nor would I say it's a great thing as it will teach you to trim correctly.
That's topping the glass right up!!
Personally if I wanted to continually find the sweet spot re trimming and bar throw, Indeed closer to true sailing I'd choose a high aspect foil on a race board, over a cloud!!.then you will really hone these skills.
