I did have a m/c, comparing to my Defiant, i will agree with Dan, the Defiant does pick up sooner, and rolls continuous, and is very strong. the m/c imo was more lane specific than the Defiant is. i did like the hit that the mutant gave me when i could use it. i feel that the Defiant will give me a better read on the lanes, and also give me a stronger and more continuous motion overall. board re-action i would say approx 3-5 more than the m/c, depending on lane conditions.
