...DMM Renegade Pro...
For a comfortable and practical (7 gear loops!) all rounder I would say go for a DMM Renegade Pro - Just under £50 from Rock and Run at the mo.http://www.rockrun.com/products/DMM-Renegade-Pro-Harness.html
I got whatever the cheapest wildcountry model is with the fixed leg loops, costs fuck all, its great.
