Nah, I really like the seat harnesses I have. So much so, that when I found one the same as mine, I bought it as a backup.
After the Guy Cribb clinic, he was suggesting that blokes should be wearing waist harnesses and girls should be wearing
seat harnesses. I am not sure of the actual reasons, but I thought I'd give it a go, because I've got one anyway.
I am still not sure if its what I am used to, or if there are good reasons. I suspect that maybe wave sailing might be better with a waist harness, but I don't do that.
Mark, I have too many girls following me around the beach anyway. I don't need anymore

They may or may not be chasing me because I ran into their kites though...
