I know this is kinda silly posting this on a manufacturer specific thread but I figured people could be somewhat unbiased for a moment and let me know their thoughts. But I was looking at getting one of the two bikes in the title. Mostly for XC and trail with the occasional DH (I'm not highly skilled so the level of my DH would be considered beginner). The Scott spark 640's twin lock system is cool to me as I always wanted a bike that I can adjust suspension on the fly. It also has a sleek and sexy design that I like. In comes the Yeti sb66 which needs no introduction and is just simply a sick bike. The switch technology is truly amazing and innovative to me being an engineer myself. the Yeti is also a bit more durable but a thousand more bucks than the spark if I decide to go with the sb66 race alloy. Any thoughts?!
