I've been in and out of the game in the past few years and can't help but notice the shift in the releases from the past two years compared to about five-seven years ago.
Around 2005 or so, Ebonite released the One as their high performance release. For a #15 ball, the RG was 2.46, intermediate diff at .027, and total differential at .056.
In 2012/2013, Ebonite releases the Challenge as their high performance release, and the RG for a #15 ball is 2.51, intermediate differential .017, and total differential at .0.57.
The snippet of my observation from the Ebonite brand is that industry-wide, the rg's have gone up, intermediate differentials have been "lowered", and the total differentials are generally close to the same. I am learning that this trend is actually changing the way I drill recent releases compared to ones from 5-7 years ago.
Today, I find that I do not have to use extremely long pin-pap distances and "weaker" mass bias positions, like I did a handful of years ago. In fact, I find myself being more assertive with pin-pap distances and MB positions to get similar shapes I saw from those "weaker" layouts I had used for asymmetric balls I saw around 2005.
Seems like today's releases allow pro shop operators and most user groups to use layouts that are more familiar to them before the emergence of those asymmetric cores were around in the mid-late 2000s.
Am I seeing this on the same level as many of you guys are? Am I missing something? Is this a good trend? I hope to start a good discussion.
