Like I said in Good Stuff:Kite harness Prolimit Aaron Hadlow Special I bought KiteWaist Pro to replace the old war horse. But that wasn't flexible enough for my liking and I decided I would use it only for snowkiting and maybe with drysuit in cold.
For summer kiting I then bought Prolimit Predator and have now used it for one summer.
It feels great, gives me the same flexibility than the Aaron Hadlow Special and quality seems to be the same high level. I'm pretty sure this thing will last as long as the Aaron Hadlown Special did.
