I have had an Immortal Spirit for the last few years. I really like it. I bought the frame and built it up the way I wanted and have enjoyed it immensely. I am 6'5" 285lbs. I wasn't sure how the cf frame would hold up to my size, but so fr so good. It's all DA with Mavic wheels, almost identical to BD's high end Immortal. I haven't had any issues with mine, but I also do all my own work, so building it up and maintaining it is no problem.
