Anyone here using a Prophet for 4x/DS and All-Mountain use? How tall are you and what size frame are you riding? On paper the small looks perfect for me at 5'10", but I can't believe the smallest size Prophet they make is as big as a medium MKIII. The 75 degree SA and 67.5 HA would actually give it a larger front center than the medium MKIII. So back to the question, can you answer it? Thanks.
