Gaines, thanks for chipping in on this one. Your observations are always helpful, and you've weighed in on this before. As someone who usually plays 17g but sometimes uses a 16L or a 16g (or even an 18g in 18x20 stringbeds), I'm always wondering about the power/stiffness/playability/feel/durability tradeoffs.
Of course, the proof is in one's own experiences. Unfortunately, life is short, and there are only so many combinations of strings/tensions/gauges one can try in a racquet before it goes dead, especially if you like some of the set-ups along the way. So, I'm always eager to read what you folks have to say.
