       | smaller bowling balls, no removing fallen pins between bowls. Its
       | different, but has fallen out of favor as a lot of the local
       | bowling alleys have closed and large chains have moved in. It
       | always seemed like an easier bowling to get started with...

         | the oil unfortunatly so people don't realize how important it
         | is to making the game fairly easy or very difficult.
         | 
         | Most amateur bowlers who are holding a 200 average in their
         | local bowling league would struggle to break 130 on the same
         | oil patterns the pros use.
         | 
         | Pro bowlers don't make a lot of money and I'd wager many people
         | on this Website have more income per year than a professional
         | bowler. But they do have an opportunity for making money on
         | endorsements for things like expensive bowling balls.
         | 
         | The ball matters to be sure. But the oil patterns used today in
         | the pro circuits circumvent a lot of it. A pro would probably
         | roll 300 game after 300 game on the types of oil patterns laid
         | on a typical league lane.

       | Pretty light on detail and its been a while since I bowled, but
       | back in college movies like kingpin and the big lebowski
       | convinced me to buy my own bowling ball. At the time it was
       | around a 150 bucks for the ball I used, and it had a different
       | material on the outside than the shiny plastic house balls that
       | allows better grip(Plastic, Urethane, reactive resin, etc). In
       | addition to the lopsided weight, you could drill it
       | differently(and fill in previous holes) if you wanted to adjust
       | the hook. I know that I was able to bowl above 200 consistently
       | and frequently would get 230-240 without much practice(other than
       | the recreational bowling). The main reason being that having a
       | bowling ball that is able to find the pocket will knock down more
       | pins. Lastly, having a custom drill to your hand and finger size
       | allows you to carry much more weight. I bowled a 16lb ball
       | easily. The house balls at most bowling alleys drill enormous
       | holes in the 15 and 16 lb balls so you have to give it a death
       | grip to hold the ball.

         | Modern bowling balls help a lot for strikes to be sure but a
         | larger influence is the oil pattern on the lanes. Most places
         | use a "house pattern" that looks like a "Christmas Tree" in
         | that the oil pattern is nearly across the lane near the bowler
         | and taper to a point in the center as it gets down the lane.
         | 
         | This pattern helps the bowler a lot since shots that are thrown
         | out too far (pushed) encounter a dry lane surface earlier and
         | the ball can begin to find traction on the lane sooner so it
         | has time to roll over and make its way into the pocket.
         | Likewise if the shot is "pulled" the ball will skid on oil for
         | a longer time before it finds traction and can roll over and
         | thus have a better chance of finding the pocket and still
         | maintain some angle to give a good chance of a strike.
         | 
         | Professional bowlers do not use a "house shot" and in fact have
         | multiple different oil patterns they use to make it more
         | challenging. In general, a "reverse block" style pattern is
         | used which means it is oily near the gutters and dryer near the
         | center meaning imprecise shots are penalized harshly. But your
         | typical bowling league doesn't have any incentive to use these
         | types of oil patterns because everyone would be awful and not
         | want to bowl there anymore and take their team to another house
         | where they can score and enjoy themselves and delude themselves
         | into thinking they could go pro.
         | 
         | This is believed to have had a negative effect on professional
         | bowling popularity as a spectator sport as many recreational
         | bowlers roll high scores because of the easy shot and modern
         | ball tech and aren't interested in watching pros who don't
         | appear to be much better.

             | 
             | I haven't watched in many years but I recall they started
             | to show on broadcasts the oil pattern being used (they had
             | 6 different types and they each had an animal name I think)
             | and the announcers would detail how the pattern needed to
             | be played for different types of bowler styles and
             | left/right handedness. Lefties always have an advantage
             | because fewer people bowl from that side so the oil doesn't
             | get pushed around as much and they can create a "channel"
             | from their own shots that "groove" the ball for them.
             | 
             | Each pattern has a different length down the lane (some are
             | long, some are short) and different application of oil from
             | side to side. A Google image search will show you examples.
             | 
             | I've bowled on them and they are humbling for someone who
             | reliably shot over 200 on a typical house shot.

             | As a counterpoint, golf courses drastically increase the

             | friction and makes the ball roll/bounce off the green
             | easier). Of course, golf is an inherently difficult and
             | frustrating sport even on the friendliest course
