I've hit with the speed mp and the instinct mp. I posted my thoughts in the other thread about 2013 speeds. Overall I think the speed and instinct are good upgrades, especially the speed. I thought it fixed several things about the IG speed that I didn't like -- more power, better feel, bigger sweet spot and improved torsional stability. Also decreased vibration. I really liked the graphene speed. Some wont though. It's stiffer than the current gen (but I think more comfortable strangely enough) and the beam on the speeds is wider which really bothers some players.
