First, it's a bit of a laugh to say this diagram makes things easier to understand, but I have a hard time understanding how each ball Hammer makes fits into a segment.  So, I made a diagram to help me slot each ball for it's intended use.  I tried to put each ball into 1. Intended Oil as described on Hammer's website 2. Coverstock type 3. Date of release.  I did this somewhat quickly and am no scholar on bowling ball release dates so there are likely several mistakes made.  I thought I would share what I have so far.

My hope is that Hammer marketing will make choosing a ball a little easier for us some day. 

Which is part of a funny conversation me and my brother have had before.

Is a pearl really a pearl?

The thought was for so long a "pearlized" ball had the distinct color difference and swirl design if you will in the coverstock versus the plain solid look of the counter parts.

Then in the early 2000's you started seeing "solid" coverstock bowling balls with that same feature of the swirled pearl design, and "pearlized" coverstocks that looked very "solid".

Then when "hybrids" came out with the mix of each it made a light come on to the marketing and how funny it really was.

Just something I found interesting from a conversation years ago.

lol funny thing is my wife still brings it up time to time (non-bowler) because she was stuck sitting through the conversation at the time.
