Hey, looking to get a CS-036 frame. I'm 6' 1" with long legs. Probably around 33" inseam. Longer arms. I was wondering if anybody has tried one of these frames and what size they got. I'm debating between the 19" and 21". I've heard the frame is a lot like a Scott Spark, I checked out their size guide and I'm right in between the two size. I plan to XC/endurance race and do some downhill and jumps. I know a smaller back is better for handling... Thoughts??
