Let me state up front that I do not know if the Penn Practice balls I'm describing below are the same ones that TW is selling. Having looked at the photo of the Penn Practice balls TW is selling, the cans have no labels. The cans I am referring to do have a label (basic gray background with some red, as I recall). So the balls I am referring to and the balls TW is selling seem to have different packaging, and are perhaps different balls. Let's hope so. Saw some Penn Practice balls the other day. About half the price of Penn Championship balls. The label read something to the effect of "Not suitable for league or tournament play" But it was also written "These balls did not meet Penn's high standards for quality due to cosmetic defects. The balls in this can are otherwise of the same quality as all Penn balls - the only difference is cosmetic." Ok, so I figured I might give them a shot. I don't really care what my balls look like. Umm... let me rephrase that... If a tennis ball bounces and wears well, I don't care about any cosmetic blemishes it may have. Function over fashion. So I began to look at the balls in these cans. I noticed that all of them were labelled 'Penn Practice' - but about half of them had additional labels. Some were additionally labeled 'Penn 2' (Penn Championship), while others were Masters Series balls, and others were Pro Penns. Most were Extra Duty Felt, but about 20% were regular felt. One can could have one Masters Series, one Pro Penn Extra Duty Felt, and one Championship regular felt. Ok - this was beginning to seem a little odd. So I kept looking at the balls, and that's when I began to see cracks in some seams. Not minuscule cracks - but big, blatant cracks. The kind of cracks that get a ball rejected during the inspection/quality control phase. This is obviously quite more than a mere cosmetic problem. A good 20% to 25% of the balls had cracked seams. In fact, there were far more balls with cracked seams than there were balls with cosmetic blemishes. It is quite obvious that these balls were balls that failed Penn's quality control. Some marketing genius decided to round up these bad balls, package them, and sell them to an unsuspecting public, complete with a label wich is an absolute and outright lie. Would Penn have committed such an unforgivable abuse if they'd not linked up with Head?
