you may feel soft when using full set Gamma Professional, hybird can give a more solid feel and enough ball feel.
In lower tension, the ball will hold in the racquet more time, but I think you may not like the feel since you play a long time in high tension.
Just look back your racquet, are you play it a long time? This racquet is over 10 years! my friend have one and recently feel that the ball not "go". I think the racquet near "finish". I'm not sure your one are same situation. If yes, I suggest you changed a new racquet since the "modern" racquet are easlier to use and most of them are more easy to generate spin.
If you want to buy a new racquet, I will suggest the follow model :
- Babolat AeroPro Drive GT (Nadal using now)
- Babolat Pure Drive GT (Li Na using now)
- Dunlop Biomimetic 200 Plus (Davydenko using one, near classic design....like your existing one)
- Head MicroGEL Radical MP (Don't select the youtek one since it's not so stable)
- Yonex RDiS 100 Midplus (classic design will good ball feel, easiler to use)
Babolat Pure Drive is Top 10 best racquet in the world (by Tennis Magazine) and many Professional are using now in ATP & WTA. The GT version is the hardest version for all generation, "Team" is a softer version. If you want more harder, you can select Andy Roddick one (315g), I'm using Babolat Pure Drive Roddick GT Plus now, it's hard enough, good ball feel 7 control, easy to swing to generate spin and can provide some power to you.
MG Radical Pro also very good (I use it 2 years before use PD one), it have a good ball feel, easier to swing but need you to generate power. Also this one will heavier than your existing one (315g) as I know that no new racquet in market now......
