When I play on hardcourts, I use either the Penn Master's Series or the Dunlop Grand Prix. Although, I slightly prefer the Dunlop, both are excellent balls on hardcourts. They hold their pressure and their fuzz well (and play well for several sessions with a ball saver). Most important, both are available in my area for a reasonable price. Anyway, spring is around the corner and I will be playing on clay more frequently. The above balls can sometimes be a little too heavy and too fuzzy for clay. Can anyone recommend a few balls that play well on dirt? Several recommendations would be appreciated, since I will then have to find out what's available in my area. Thanks.
