Muscle Power Frame - Effective??

[Mike]

just wondering if MPF really helps?
does it allow longer lasting string tension
and more power?

MPF does wonders! it helps you generate tons more power because its more weight at the head. i dunno about string tension tho.

It also can have more string tension because of the rounded grommet"heads" on top of the racket.
