I will share this with you guys for free because I like to party. Now, this may or may not have been already present on the wilson pro staff tour 90 but I traded the racquet long ago and can't remember. This may sound crazy anal but I texturized the outside throat of my racquet. It is very subtle but it creates a landing strip (tm) for my hand when prepping the racquet head. It is very sweet on the vanity one hander. It is not a game changer but it is a feel enhancer. I feel confident that landing strip (tm) technology could change the game.
