Count me in as someone else who would really like to know. The obvious difference is the Speed is 18x20 and the Extreme Pro 2 is 16x19. Other than that the specs look really close! It received good reviews from TW staff as well...just a hair under what the Extreme Pro 2 got. I like the fact that it is even more headlight than the EP2. That racquet might just be a hair too heavy for me in preference.
