Mi 2 is right. Look at the Ogre line that was out for several years. Particle Ogre to handle lots of volume, Orange Black Solid reactive that was a step down in handling oil and was as smooth as butter...the Blurple Ogre that was the pearl version of the Orange Black, another pearl Ogre that was a skid/flip monster, and finally the urethane Ogre that brought back almost the same coverstock as the Pink Hammer and went almost as straight as an arrow and needed significant friction to transition from skid to roll.
Other than a super oiler and a plastic, everything was pretty much covered in 5 balls, 1 core design.
Plus...look at Storm. If someone would buy every ball on the market, how do you really carry all of those to a single league session or even a tournament? Most folks carry 4 or 6...some might carry 8, but that is extreme and rare. So how many balls do you really need out for someone to make a full arsenal? VBP does a good job covering reactions with minimal releases.
But, everyone is different. You may not like them or the reaction you get. Who knows until you try one.
The lanes were so fried last night I had to use my Blue Green Centaur which is a super low diff ball from almost the start of the night and finished using my Track Spare + as a strike ball. Must be oil saving night or week or something at the bowling alley, but the point is, VBP still had a ball that allowed me to play where nobody else could even think of playing. Granted, the Blue Green Centaur is long gone and odds of finding a new one is almost nill, but at one time, this was one of the greatest niche balls available from any company.
