In reply to nignogbob: I really like mine - I've used it for sport, trad, Summer Alpinism, Scottish Winter mountaineering and pure ice climbing. Comfortable, lightweight and folds down small for squeezing into rucksacks.
But as with any harness, you really need to hang in it for at least 5-10 minutes to see how well it fits. I tried it, along with the super-light S240 model, and found the S240 really uncomfortable after a few minutes. The R320 fits me perfectly though.
