I've been following this thread with great interest. I find the observations you've made very compelling. So much so that I've abandoned my big racquet bag, a Wilson EcoTour Super Six, in favor of just showing up with two frames and a water bottle. Oh, and keys. And phone. And wallet. Actually, I don't usually have the water because my club has water coolers on court. But I sometimes have to have my asthma inhaler with me, just in case.
By my count, this means I carry about 6 items on court with me. Sometimes I use a waist pouch to put these things in, but club security will sometimes stop me because I look like a tourist. Other times, I just try to wear shorts with very big pockets.
But I digress.
My results on court have been mixed, which has left me a bit confused. I mean, my results were also mixed back in the days when I carried the racquet bag. I fully expected that after ditching all this gear, my game MUST go up. After all, I'm freeing myself from the trappings of equipment that has weighed me down.
It was not easy divesting myself of the grips, extra shirts, can of balls, etc. And the cost to me personally has been high: I sweat a lot and my grips can get very slippery. I've broken 2 frames while serving because I no longer have extra overgrips that I carry with me in the bag I no longer use. It's also gotten harder to get people to hit with me at the club, because I'm now known as the "that guy who never brings a can of balls." Even worse, I've convinced other people to adopt this "no bag" philosophy of yours and I've actually been on court with an opponent who also did not bring a can. We had to go around the courts trying to find used balls to hit with. I think that match might have ended in a draw.
Anyway, I am still committed to the elite club of you "no bag" players. But I really want my results to improve. Do you think moving from the 6 items I bring on court to say, 5 items will help? My other thought is that while I've lived in Asia, Europe and now America, I do not currently reside in a world capital. I mean, I've lived in London and New York, and San Francisco is a nice city, but it's no Paris or Moscow. Do you think moving to another world capital will give me access to the great insights that you've exposed us to?
