YankeeJim: This becomes moot if you have X number of tries, say 10. But every time you think something might work, up pops that friggin $ sign and if the idea restricts sales, forget it. A necessary evil of the game, I suppose. :-(
After doing so last year, even up to the qualifiers for the Fall and early Winter Tours, I have vowed to never again enslave myself to qualifying for anything. The last three Winter Tour legs I attempted only two or three times, the last only once (shot a 56 and qualified for the first time ever). I'm sure I'll give these more than a cursory shot, but I'm not going to turn it into a second job. I dunno that I'll give it more than 10 tries.
But yeah, WGT makes a mint off of balls during the qualifying for these things. They are not going to slaughter that cash cow just yet.
Edit: Actually, I probably will try it a lot more than 10 times, but more to learn the course than trying to qualify. It's different with a brand-new course.
