What racquet for my stlye of play? - 4 x 4 swing sets blueprints

First, I can not try new clubs that I live on a small island with no commercial courts (Saipan)
I played for 8 months and won the 3.0 division.
Now in version 4.0, I noticed the lack of power but good control with my racquet Head Liquidmetal Radical OS, suspended by a rope made of Kevlar with 57 years of age and stress Technifiber X-61 One tension.
Base is used to play a long swing.

1. Is there a way to increase the power of sacrificing too much control.
2. Is it better to use a tennis racket medium (90-110 cm ²)
3. Is it the cable or the bat in my power to improve, or is my swing.
4. How to compare Wilson and Babolat racquets Liquidmetal head.


Thanks
