i have often commented on playing lower level tennis than my ranking and how it wont help my game.. for all of you out there who think by playing "only" with better partners in dubs to "improve" your game, your nuts.. i play 8.0 mixed where i'm the weak link in a 3.5/4.5 partnersip, I now have a better respect for my 4.5 partner and the pressure he's under. i play 6.5 combo where im supposed to be the better player. this is very hard to do! try it! it will make you focus and really think: you have so much pressure to: 1. Be consistent 2. make your partner play their best 3. take the leadership responsibility on the court. 4. change what you think is your game to pressure the weaker opponent. 5. protect your partner! i challenge you out there! can you do it!? im now convinced it is VERY good for your game.. AND remember..someone did it for you..
