What is a taper profile? The bigger the profile, or the more, what does it really do? Isn't it for power?

i think thats the technical word for putting more weight on the head of the racket

I think the Ti 10 is more head heavy than Ab 900 or Ashaway power Kill 90 or any other Triple taper system racket.

Triple taper system is where the racket head has 3 different widths. The widebody near the shaft and the thinner width near the 3 o clock postion adn the widening again at the head.

What it genarally does is add more weight and supposed to be different in swinging too.

I have no clue abt how good the aerodynamics is but i guess u can smash hard with triple taper rackets!

Yes, Yogesh explained it quite well.

The idea behind triple taper profiles is to make a light racquet that still has some of the characteristics of a more heavy racquet, i e good control and lots of smashing power.

to put it simply... the triple taper racquet, is supposed to combine the characteristics of a racquet with good control, and power into one light weight, well balanced package.

Hope this helps.
