I borrowed my friend's MP-55 @ 21lb for an hour today and played with it. I found the racket is very great at smashing but a little too heavy headed for me. (I use ISO 60Light which is a 3u racket) Now, I want to buy a new racket as I want to delivery more power to the shuttlecock when playing. I am not strong and I am only 115lbs but I like smashing the shuttle a lot. So I want to find a stiff heavy headed, but light (3U) racket. Do the experts here tried both of these rackets? Do you think MP-33 can give me the good smashing feeling as MP-55? If MP-33 is not good for me, what other rackets would you recommend? Thanks for teaching me how to choose rackets.
