How do the not so good pros survive on tour.  The guys who never win.  Where does their money Come from for expenses and entry fees.  Do the top guys get a salary from the ball companies?  Does a percentage of what they win go to anyone?

Lots of good responses.  Only thing I can really add is that it wasnt much better 40 years ago.  I went to my first nationals in 1975.  A team mate told me beforehand that I would be surprised at how many good bowlers werent on tour and how many mediocre bowlers were.  Many of the tour regulars back the were out simply because they had better sponsors than job prospects back home.
