The SX is definitely stiffer. It is the stiffest out of the SP series. As for head heavy, I'm not sure on that since the MP77 is pretty head heavy itself. Yodums
I have the original silver/black Ti-SP sx. It's pretty head heavy, a lot head heavy than any racquet i've used. The mp77 in my opinion isnt as head heavy as the sx. I can sure get a lot of power from it. My jump smashes were really good. I could feel the weight of the head as it goes thru the air. Feels pretty good in my opinion, this racquet is a pretty good forearm builder when you drive with it.
oh...is that really head heavy??? i can make a great smash with my friend's mp77,,,,but some problem with my drop shot and net when i play ..... then is it better for the sx?
i wouldnt say its better or that it isnt, it all depends on the player. you should try it though, you might like the tisp better than the mp77.
