If you want my opinion, I'd go for the waist harness. I only started kiting at the beginning of tthe year and the shop said that the seat was the go to begin with but I have since traded the nappy for a waist and it was the best thing I've done. When you start up, you will be doing heaps of walks of shame and it is no fun with a nappy on cutting off the circulation to your legs and pushing your nuts into your guts.


. The waist rides up a little and you'll be a bit sore for a while but I've got used to it now after only 2 weeks of using it
