I admit this is really up for grabs depending on definitions, but at what technology stage (frames and strings together - same era) was/is the pro game most enjoyable for you to watch? Not the personalities, the game as the technology defines it. For me, I enjoy watching varied, skillful shots; athletic ability on display; and a speed of game where serve&volley as well as baseline can flourish. In my mind, with too little or too much power, the balance is gone. For my mind's eye, the Original Kevlar Pro Staff/ Prince Graphite (with nylon /natural gut) era seems about right. I most enjoy the game with phenomenal talents, speed a foot, and varied shots. The power wasn't oppressive yet (no poly, thank goodness)- and cancelling out many aspects of athleticism. I was reminded of this recently when viewing (actually totally enjoying - in awe) Fed/Sampras ('W" - 5 sets) and Edberg/Chang (US Open semi - 5 sets). I would also (as a second position) take the modern wood era - a little extra stiffness went a long way... What was/is the technology era(frames and strings)where tennis at its "best" and suits "your view of the game?"
