crap thrown their way for using "old" designs in cores and covers - Elite, Lane Masters, to name a few were hated. Now bigger companies are starting to run out of ideas it seems and redoing old "vintage" balls.
From different "batches" you're not going to get the exact same ball. I have owned 3 hyroads from different years, two of which had the same layout. The current one I'm using, 2012 seems to have a quicker response off the dry. The first gen and second ones were a bit smoother.
I'm not well educated on ball tech and design, but I think you can only do so much to a ball before you start "renaming" and using fancy words to sell the same ball and ball design. This is the reason I buy mostly balls on clearance.
I've used storm strictly for over 5 years and I did okay. No $$ made and no honor scores, but I loved the hyroad on sport patterns. But using smaller companies like Lane Master, Lord Field, and Elite I have cashed and raised averages. In fact, I got a radical Rave on $49.95 at buddies (not really a big name company) and less than three months I made just under $500 with the ball. shot personal best (cashed) at the stadium on a non THS pattern (700+, 689) using lane masters and Lord fields with old designs two piece cores. With Storm, brunswick, and Ebonite, I haven't had the same experience.
Anyway, I don't follow ball companies like many of you, it's just I noticed over the last couple of years and most recently, there are more "remakes", "vintage", or name tweaks of an old ball from the past by the bigger companies.
