Extremely capable bike, no need for other bikes now, the Stumpy Evo does it all for me. BB height is a consideration when riding tight rocky/stumpy trails, but you soon get used to it and I've had pedal strike related stacks on bikes with much higher bb's - reading the trail and pedal timing is the key. No complaints with the efficiency, seated/climbing it's as good as anything I've ridden in this travel range. Standing and pushing hard there is some movement (despite shock setup) but it's minimal and still better than many. Have always preferred Horst-Link bikes over anything else for overall performance, and am not a believer in the term "over biked" - you ride what you choose to ride right? so to have a bike that's solid, stiff, fast, nimble and fun to ride, storms descents and isn't a chore to climb on means there's little I can complain about. Only niggle has been the OSBB - creaky with the threaded bb adaptor and took a few removals/re-fits to fix. Mine's a large, feel free to mail if you are in the south east and want to try it.
