Mmm, I didn't make your point. In football every competition, usually has different kind of balls. Oh, and every player can use the football shoes they want. So not everybody uses the same equipment. If a player is accostumed to playing in the italian league, and another is accostumed to playing in the spanish league, and the champions league ball is more similar to the spanish league ball than to the italian, will the italian player moan about an unfair advantage? No, he'll adapt, because that's what being a good player means, adapting to the circumstances. You fail, hard.Those high-tech swimsuits should be banned and they may still be. I think the jury is still out on that one. Swimming is about who's physically a better and faster swimmer, NOT who's wearing the most high-tech swimsuit!
And thanks for making my point with your football example. In football, everyone on the field is playing with the same ball, aren't they? That's my point about standardization in tennis! Everyone on a tennis court should be playing with not only the same ball, but also with the same racquet. Discrepancies in equipment makes it inherently unfair due to the superiority of one racquet over another. The differences in equipment should be eliminated as a variable in the outcome of a sporting contest. The winner should be the best player, NOT who was using the best equipment. If you can't understand that then you don't like to play games fairly and on a level playing field.
