even though their physical size (width, not length) is somewhat similar, the skis are completely different... the First Bloods are soft flexing and pretty damn buttery, while the MSPs have a substantially stiffer flex pattern - I ski the MSP almost everyday and think it's an incredible ski for all mountain skiing, park included - it won't wash out on big airs too... the base material on the MSP this year is a bit thin, but if you don't grind it too much on a machine, it'll hold up fine... my two cents
