I'm playing 6.5 combo right now in USTA, and coming from mostly singles play, I'm still adjusting to the whole doubles game. My strategy when hitting from the baseline is to usually hit cross court or low over the net towards their feet. The only time I lob is if I'm running for a ball and have no chance of controlling a topspin shot so I just go for a defensive lob. Anyways, my partners and opponents often will lob almost exclusively when at the baseline (except when returning serve sometimes), but some of them don't really have much authority in their topspin strokes anyways. Is it a good strategy to use the lob this much, or should it be used sparingly? When your partner is serving and the returner is a lobber, is it better to stand around the service line, rather than the front third, to handle the lob? Also if you are serving and the returner is a lobber, is it better to stay back rather than S&V? Are there alot of lobbers at 4.0 and 4.5?
