I was in a similar position recently. Ive just returned from living in Socal, daily ride was a Demo 8, perfect for the stuff we were riding. Generally the other guys were on V-10s and older Giant Glorys, so big plough bikes. Trails were big chunk, 10 – 20ft drops and some big rock gardens.
Before I came back I gave some thought as to what I should bring back. I swapped the Demo for a freeride build. A KHS Lucky 7, exaxtly the same frame as the Azonic B-52 over here. I tried to build it up as light,as possible so it would be ‘kind’ of rideable. Zochi 66s (180mm), swapped the Van R coil for a Roco WC air can, light DH wheelset but still 1×9. Came in about 38lbs. I could just get away with taking it on the AM trails.
That for me is perfect for session days at Woburn, Chicksands and Aston.
Worth look at something similar, SC Bullit, Demo 7, SC VP Free with a 180mm fork.
