18 chrono def better than my 19 edge in light wind
I have put it in the water about 5 times, so far on all occasion I have re launched it, but if on the 19 I reckon I would have been packing up on the water at least three of those times.
in around 7 knots it is easier to get planing with the chrono.you do need a nice big area to launch and land and if lots of sticks and things it can be a potential problem with them getting caught in the thin bridles, so if you are one of those guys that goes off his nuts yelling and blaming equipment for everything that goes wrong then dont buy a chrono, you will cause embarrassment to you and your family will want to hide under a rock

Launch with kite down wind in light wind is easy
bringing the kite down low to water in very light breeze can be a problem as the wing tips can fold back on the kite, but this is only while sitting on beach or changing direction and only going slow while diving kite to get power.
All in all once you get to know your equipment, what you can and cant do you will enjoy the gear.
All my experience is on a race board for racing, this makes the downsides of a foil worth it as there are more upsides, if however I wasnt racing I would only suggest a foil if there was no other option for a LEI to have fun on the water.A foil board should also be a great option, you can cover an amazing amount of ground, you have some great places to explore up there and you wont need a permit unlike if you drive a car
There are some vids of guys doing a few jumps and things on them, but it might be best to learn in some other water as while learning to ride one there are many thing to be worried about beneath the surface up there. A foil board would also only be for high tide as you need about 1.2m water to get going in

especially when learning.
