After doing some testing, my girlfriend decided to go for the Babolat AeroPro Drive Cortex racket in stead of a Head YouTek Extreme MP or Head MicroGel Radical MP. She tried all three of them, including a Prince O3 Hybrid Pink which she hated. Of the first three, the YouTek Extreme seemed to be kind of dull and worse to play with than the MicroGel Radical. She really likes the latter, but liked the Babolat AeroPro Drive Cortex even more because of its Cortex system. It really does a good job absorbing the vibration, while maintaining ball contact feel. So, after the intro it's time for the strings. She tested the Babolat with Toalson Rencon 1.25 Red strings, probably at 25kg tension. I don't know the tension, but I can assure that I've never ever hit a harder serve than with this racket and these strings, it's ridiculous how much power comes from it. But that's the whole thing, it's too powerfull for my girlfriend. She likes some power, but more control than these strings can give her. So I'm now looking for the best allround string for her, which does give some power but not too much, while maintaining good control and feel of the ball. Both Head rackets were equipped with Toalson TOA Gold 1.30, which seemed to give more control and feeling, while still maintaining some power. I have the choice between the following strings: Big Banger Alu Power 1.25 - power/durability Big Banger Original 1.30 - power/durability Head Rip Control 16 1.30 - comfort Iso-Speed Energetic 1.20/1.30 - comfort Iso-Speed Professional Classic 1.20 - ? Penta Synthetic Gut 1.30 - allround Toalson Asterisk Spin 1.30 - spin Toalson Rencon 1.25/1.30 Red - power/durability Toalson Synthetic Tournament 1.38 - allround Toalson Thermaxe 1.23/1.27/1.30 - power/durability Toalson TOA Gold 1.30/1.35 - allround Toalson Tour Natural 1.30 - ? Wilson Sensation 1.30 - allround Wilson Sensation 15L 1.35 - allround So could you please help me decide which is best?
