Hi Guys,
There is no doubt that the seat will reduce back pain, and as a long time sufferer of a bad back I need a well fitting harness which allows me the freedom of movement to ride the way I want.
Personally I don't like the seat harnesses because they just feel too restrictive for the way I like to ride. I ride a combination of Unhooked, hooked in power freestyle, kite assisted freestyle, kiteloops (bad for the back) and also for surf riding on a surfboard.
With the range of different diciplines and styles, the only way I can really achive the riding I want is to use a good waist harny. This years Flying Objects Waist is really nice. It has enourmous back support (which initially took a while to get used to) and can slide from side to side for hooked blind and toeside and also works well sliding for waves.
As a beginner, you would be better served by a seat as your kite will spend a bit of time at 12 o'clock, but as you become more accomplished, you tend to ride with the kite lower and will appreciate the waist for the added flexibility it offers.
So my advice is to start with a comfy fitting seat and once you start freestyling, check out a comfy waist. Go into a couple of stores try on everything, both seat and waist from all manufacturers, in your size and hang from a rope to get a rough feel for what it's like. Buy the one that fits best and feels most comfortable regardless of price, your body will thank you for years.
Good winds,
