There was a thread posted earlier regarding the Teal Rhino Pro.  Several people were wondering what the cover/core combination was.  I was very familiar with the Rhino line of bowling balls having thrown almost all of them in the past. However, I am old and my memory isn't what it used to be.  The Rhino originally was a black urethane ball with a pancake core.  Following the Black Rhino came the Gray Rhino and Blue Rhino.  Both of these were also pancake weight blocks. The Blue Rhino was a sky blue color.  There was also a Cobalt (dark) blue Rhino released as well.
   The first reactive Rhino which was the "Rhino Pro" line was the Purple Rhino Pro.  That ball had a light bulb shaped core and a very skid/snap type reactive coverstock.  The Teal Rhino Pro was next in line and it was not polished like the Purple Rhino Pro.  It also had a light bulb shape for the core.  These cores were very popular with all of the manufacturers at this time.  The next step was the Rhino Pro Gold which inverted the light bulb core from the previous two releases.  After that there were others released.  The Rhino Pro SE I believe was one of them.  At this point the manufacturers started to go insane releasing ball after ball constantly.  

    I hope this helps.  If any of this information isn't 100% accurate, I'm sure the sharks will let me know!

Good bowling everyone.

The Rhino Pro LE was a blue reactive ball with a core design that would find it's way into the Johnny Petraglia LT-48 Gold, which was made in 1997-1999.

Let's see if my memory is correct.  Since I was getting unlimited Brunswick equipment at the time I had quite a bit of them.  These are in the order I remember after resin was introduced:

Purple Rhino Pro (solid resin)
Teal Rhino Pro (solid resin...earlier and stronger than purple)
Blue Rhino Pro (solid urethane with same core as teal)
Gold Rhino Pro (pearl.  Extremely strong at the break... Much higher diff than Teal)
Slate Rhino Pro (solid grey.  Same core as Gold.)
Pro RE (3 different versions.  Blue solid, light purple solid, green pearl...high RG and huge solid core. )
Pro LE (dark blue solid cover.  lower RG and extremely high differential.  I think about .50 and was later remade into of LT-48 Gold)

That was over 15 years ago so there may be a few errors but that's what I remember.

Yeah I think it was urathane:

Black, Blue, Grey, Wine, then Colbalt.

Reactive

I believe the Teal was the first pro to come out. The the purples, and golds.

Then They released the T2 which was the first to have the inverted bulb core.

Don't forget the Rhino X  Copper.  Same core as the T2.

It would be nice to have a timelime of all of those with pictures lol.
