Do you know when you'll be in town for the tournament? I ask, because I have on very good knowledge that they'll be laying down last year's pattern, which will be similar to this year, as well as various other sport-compliant patterns at Gold Coast. I know that when I was there on Monday, they had laid out Seoul, Mexico City, Los Angeles, Paris, and last year's USBC Nationals pattern for practice. So if you have the time outside of the scheduling that BJI and the practice session, you could try there.
Outside of that, if a local house is willing, you could lay out last year's pattern, as there shouldn't be much changes, though keep in mind that the surface will be different, though shouldn't be a significant difference.
