Komike - I bowled the Spring National at Sam's Town in 2001 and 2002.  The first year, the cut was +68.  The lanes were tight during qualifying early in the week, but really started to fly by Thursday and were scorched for the semi's.  The Masters cut ended up being +68, but had been +104 when I bowled the noon squad on Wednesday.  

2002 was a different story.  The cut was +44.  They used a variation of the sport shot and I was throwing 17-12 and missed the semi's by 17 pins.  There was definitely an out of bounds beyond 10.  If you don't already do so, I'd recommend plastic for your spares, especially for the right side.  3-6-10's were an adventure if you used reactive or particle.  It either went in the gutter or chopped the 3.

Good luck, have fun, and please post how you did when you get back.
