I use a Dakine but bucket style harness for distance racing - the most comfortable harness I've ever worn. I used to use a Magic Marine Equipe with foam pads stuck inside to relieve pressure on the hips - that was pretty good but our ground crew lost it last year.
For round the cans I use a magic marine but bucket - not amazingly comfortable - but not too bad and the races don't last too long
The Zhik looks good - but it's hard to space the cleats for chicken lines on this design - much easier with the spreader bar style.
