Long Lasting Tennis Ball

I spent 3 hours( 13 games) one morning playing with the Penn Pro 40; it's a very interesting ball. Our group normally plays with yellow Duras during the warmer months but I 've been experimenting with the new Gearbox GB1, Diadem Premier Power and Selkirk Pro S1( only one day) the last month or so. All three balls weighed 26. 1 grams and around 73. 5mm in diameter. It uses the hardest plastic of any ball I 've measured at around 50 shore D; yellow Duras are around a 48. Bounce height was about 1/2 '' higher than a Dura but the same as the Diadem and GB1. The seam( yes, they are an injection molded ball) was obvious but it was n't very pronounced and no worse than the typical molding mark on rotomolded balls; I do n't recall it ever effecting play. Being a injection molded ball it does have the appearance of what most of us would consider a cheap ball. The Penn Pro felt a hair firmer than a Dura but at the same time was easier to control. When warming up hitting groundstrokes the ball seemed to stay on the paddle face longer resulting in better control and extra spin. I felt like I could shape my groundstrokes better than any other ball I 've hit. There is a sensation of the ball compressing the paddle face as opposed to the paddle compressing the ball. Consistency was a word that kept popping into my head all morning; ball flight, feel, bounce, etc. When hitting drops, dinks or other finesse shots the ball seemed to always behave as expected. I ca n't recall us getting an odd bounce all morning either. With all of the above said, it definitely feels/sounds different than a roto- molded ball( not in a bad way). As such, many might initially dismiss it before giving it a chance. I found myself liking it more and more as the day went on. The ball did n't seem to lose much in the way of firmness as the day progressed either. As for durability, we played 13 games with a single ball and I ca n't find even the faintest indication of a crack. It 'll need more games before I can provide a true report on the durability. The oddest thing about it was that it left a LOT of ball marks on my court yet did n't do the same to my paddle face. I 've gotten a random ball mark on the court before but the Penn Pro left them everywhere. I 'm pretty sure this is due to the hardness of the plastic where it will shear off as opposed to just deforming.
