Our AD bought us Champro practice balls for, well, practice and I can definitely tell a distinct difference in even hitting those balls, let along how horribly they hold up.
Champro....wow, they are still selling baseballs? I had a sporting goods store for quite a while. Champro was ok for equipment....bases, catchers gear for younger ages, etc, but their baseballs were by far the worst I ever saw. Even their best practice ball was good for no more than about 6 hits before it had a noticible dent or worse was more the shape of an egg than a baseball lol
Yes, Champro has historically been a budget/price point brand with relatively low quality and that has certainly included baseballs. However, again, you can find diamonds in the rough. A while back, they made a run at entering the high end baseball market. A few models were quite good. And since they were not able to gain any significant traction in the performance ball market, there were closeouts. For two years, I was able to get a professional grade baseball from them at the price of a moderate practice ball. Best practice ball we ever had by far. Like I said before, if you get educated on cores and covers and get a feel for "the feel", you can shop smart with baseballs.
Conversely, Diamond was always known for a quality practice and moderately priced game ball. But, for a 2-3 year period, they changed the cover on one of their most popular practice balls, It was way too slick. First time I grabbed a new one, I knew it was time for change.
