Well I've been riding a Rocky Mountain Element for 4 years now... and with the weight gain and more travel going to the 575 I was worried it would be harder to pedal up hill, but it wasn't. The more technical climbs actually seemed smoother than on the Element, due to the longer but efficient travel. For a 5-3/4" travel bike that comes in under 29 lbs, I'd certainly recommend trying out the 575.
