Tom,
 
    Most the information about our products is available on the website but I can give you a general run down of the product lines.
 
 
AMB line (discontinued due to the change in RG differential rules by the USBC - but still available and legal to use in all USBC competitions - we just can't produce them any more.)
 
AMB Particle is a very aggressive oil ball.  Designed for heavy oil with an early arc reaction through the entire lane.  Can burn up and die on the back if there's not enough oil or ball speed.  Won't be flippy on the back no matter how it's drilled.
AMB Solid will go longer than the particle and have more backend.  It's designed for med-med/hvy oil with a strong arc reaction.  Can be drilled to roll earlier and more arc or longer with more flip - but won't be snappy.
AMB Bronze Pearl will go the longest of the AMB series and flip more on the backend but because of the flare potential it still won't be a skid/snap reaction.  Good for med to med/light conditions.
******************
 
IMMORTAL line (discontinued due to the change in RG differential rules by the USBC - but still available and legal to use in all USBC competitions - we just can't produce them any more.)
 
IMMORTAL solid will hook a little more and little sooner than the AMB solid.  Designed for med-med/hvy oil with a stronger move overall than the AMB.
IMMORTAL pearl will flip a little more on the back for most people than the Bronze because of the cover but can be made to roll earlier than the Bronze with early drillings because of the higher differential.

GRYPHON line
 
Frankie May GRYPHON will make a stronger and sharper move on the back than the AMB or IMMORTALs because it doesn't flare as much or roll as soon.  Surface can be easily adjusted to fit most conditions from med/hvy to med/light.  This is a very versatile ball.  
G-3 GRYPHON will skate much longer and snap more on the back than the FM Gryphon or either AMB or IMMORTAL pearls.  This ball definitely gets down the lane and then unloads with a kick on the back.  Good for opening up the lanes or when you have to move inside and cover a lot of boards while needing recovery on the backend.  Too hard to control if the lanes are drastically over/under reactions.
*******************
 
OGRE line
 
OGRE solid will get down the lane easier than the AMB and IMMORTALs with a good roll and predictable read.  Not quite as strong as the FM Gryphon but still a good med-med/hvy oil ball.
OGRE pearl (purple/black) will go longer than the solid but start sooner and handle oil and carrydown better than the SS Ogre.  Good middle of the road ball to start with - then go to the solid on more oil or the SS on lighter oil.  
OGRE SS will skate further than the purple pearl but flip harder on the back.  Like the G-3 its a good ball to open up the lanes or play deeper inside lines needing recovery on the back.  Not quite as strong as the G-3 for most people.  
OGRE particle will hook more in the oil than all the other OGRES.  The particles give it more grab than the Ogre solid but it won't burn up early like the AMB particle might.  It is much easier to get down the lane than the AMB particle and offers more backend but it won't handle an extreme flood as well as the AMB particle would. Good for med-hvy oil

GLADIATOR line
 
GLADIATOR solid will give an earlier midlane roll with a controlled arc reaction.  Starts sooner than the Ogre solid with more of a sweeping arc motion.  Good for evening out the over/under reactions found on touchier conditions.  Good for med-med/hvy oil.
GLADIATOR pearl will go longer and save more energy for a sharper backend then the solid but will still be an arc motion just harder and a little sharper.  Handles longer oil better than a lot of pearls because the core gets it into a roll sooner.  Will start hooking sooner than the SS ogre and even the purple Ogre pearl for most people with a more even predictable reaction than the Ogre line.
 
 
All in all -
Crankers needing more control will like the Gladiators and Ogres
Average bowlers will like almost all - preferring Ogres and Gladiators for their control and predictability.
Those needing help hooking the ball will like the AMB, IMMORTAL, and GRYPHONS
 
 
Hope this helps,
 
Jim
