Well.  I'll try to answer this.

If bowler A can hit the same board 95% of the time at the same speend, with the same number of revs...I would call that more consistent than actually good.  the number of revs it takes to hit the pocket I think is irrelevant.

I would say that bowler A is better than bowler B if he has more ways to get into the pocket than bowler B, regardless if bowler B's 'A' game is better.  I say that because bowler B's 'A' game isn't always going to work every single time out.  If that was the case, we'd all be pros.  Versatility pays.

Not necessarily.  Bowler B may not need to make a ball adjustment.  If bowler A makes a ball change, and keeps striking...and bowler B doesn't make a ball change, but keeps striking..then it's all the same imo.

Yes, I would say that bowler A is better if he can play multiple areas.  A person who bowls on a Cheetah pattern(just an example) absolutely cannot throw the ball that same way if he was on let's say the Shark Pattern.  Once again, verstility pays.  Even the climate differences we face throughout the year causes us to throw on different lines and angles.  Bowler B may be more accurate on one set condition-but this is exactly why we have more than one condition.  Once again, versatility pays.

This one is kinda hard to answer.  I don't think there is a "dominant hand" when it comes to the game.  I think they both have their advantages and disadvantages.

The last one, I would call more experienced.

In today's game, I think what defines a skilled bowler is:

1. Being mentally prepared is the best part of your arsenal
2. Making the best shot you can make everytime.  We'd love to throw nothing but strikes, but this isn't always the case.  The easier the spares we leave for ourselves are, the better scores we'll have
3. Being able to play that different angle, speed, hand release, etc.
4. When something goes wrong, you don't put the blame on the house or the lane technician, you start brainstorming how not to repeat that errant shot.
5. Knowing what your equipment is supposed to do, and when it's supposed to do it.

High game-300
High series-796

Current Arsenal- Track Power Machine, Ebonite Total NV, Track Phoenix, Track Mean Machine, Track Phenom, Track Equation, and Track Silencer.

Look at it this way there are pros who shine on certain patterns and not so much on others.
 I think its a comfort zone of the a game that can get the best out of you, im not saying you dont need to get all the skills and knowledge you can,if you want to bowl in a lot of tournaments and such.
 but if the guy with the single game plan gets matched up with his condition and everythings flowing, he is gona be hard to beat by someone that is not in there comfort zone or a game.
This by no means says the a game is better in the overall picture but anyone can be beat at times even the best of them on a bad day.

life is short enjoy it.

the skilled bowler reads the lane and creates area for error for himself. also he can adjust according to what he sees and make the move before sorprises happen

the req for skilled bowler:

flawless approach:
1- swing motion is fluid
2- not muscling for the release (free armswing)
3- able to land the ball smoothly on the lanes (unless loft is wanted)
4- balance at the foul line, as well as start and end where is intented(footwork)
5- consistency and accuracy (for both strike and spare)

equipment selection and bowling knowledge in general:
1- ball selection, surface and drillin, and shoes to use
2- lane strategies

the above is essencial (there are more items obviously) for anyone who participates in tournaments

thats skilled bowler, but professionals they have to know more stuff
--------------------
When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment

When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.
