IMO, the one and only goal in tennis is to keep the ball in play. If you can't hit it within the lines of the court, you can't win. It doesn't matter if you hit with a ton of TS, or if you have 65 mph groundies if they don't land within the court.
This sheds light on how my game has been. I would always use a long, smooth (measured) stroke using multis. I've been trying to incorporate poly strings into my game without great results, until recently. I'm learning the unit turn and a modified eastern grip, from eastern, on the forhand side. I've started getting results from a much faster stroke using a poly/multi hybrid. I'm also switching to a ohbh, but that will take longer before I see progress.
