Yes, yes - demanding rackets will make you better. But how about another question; what are the easiest rackets to play with currently? In other words, practice schmactice - today, I just want to have a good time. I'm talking borrowed stick, no mods, "Hey, I could actually play a set right now" first time out, fun for everybody rackets. In my own experience, there's only really two out there: the Wilson Surge and the Prince Shark. Neither are perfect, and both might have a little too much/too little mass, swingweight, stiffness, headsize, power, control, etc. But in the end, they've both got big, even sweetspots and behave pretty much exactly like you'd expect. Enough mass to prevent excessive wrist flick but still light enough to not distract you from playing (as opposed to getting big timber back and around on time). One could argue that the Head Liquidmetal 4 and Pro Kennex 5g might squeeze in at opposite ends of the conversation as well. Maybe the LM Radical, too. Pure Drive and its woofers might be a little too hot now and then. I've also seen non-dedicated, but athletic, part-timers play some pretty good tennis with Prince Screams and Wilson 6.X Hammers as well, though I personally find their head heavy balances a little strange. Any others? The thought occurs to me that there's pretty good overlap between these particular rackets and Tennis magazines Editor's Choices. Maybe they know something we don't, after all.
