You know, bowling is a tricky sport. The fact one person can score really well with a ball others can't score with, The fact one bowler can score really well at a specific ball speed when others (at that speed) can't, The fact one bowler can carry the corner pins when others can't should raise an eyebrow or two.

When talking "Baselines", well, baseline IS the name of the game. Baseline hand position, baseline ball path, baseline ball speed, baseline axis tilt and rotation, baseline ball reaction.

The best arsonal is one where your equipment has the ability to overlap to some degree. NO HOLES. Norm Duke said that Professional Bowlers are the best in the world at changing their ball speed. Ever wonder why they put so much emphasis on that? Or, how much practice time they've spent developing that ability?

By changing ball speed, that in itself gives you a different look, while using the same ball. Slower, more midlane read. Faster, easier path to the breakpoint. Of course, your entry angles still have to be there but that isn't ball speed as much as ball choice. It's not enough to simply chose a variety of balls, you need to know the intended reaction of the layout. It's not enough to simply chose a variety of layouts, they need to match up to the ball and your style.

I wish someone would come up with a graph to go off of, but so far we are left to our own "best guess". In the CNC world, we have slide scales. X amount of RPM's by X size drill equals optimal Feed Speed. Still, nobody (in their right mind) would try and feed a drill into stainless steel like they would aluminum. So, other factors are present. Bowling is the same thing, OIL LENGTH and STRENGTH (resistance).

You can get pretty much any ball to the pocket, but it's pretty obvious that isn't good enough. don't matter how hard you try, it just won't carry. On the flipside, you can put a ball anywhere near the pocket and it will carry. This is when you know you're getting close to figuring something out that works for YOU. Simple fact, you will never get to that point by throwing the same strength equipment. You have to have a wide variety and you need to learn to read the lane QUICKER. That takes time, time you have spending on practice..
