spectral, take a look at the recreational series patterns which represents what a THS could look like at the kegel site:http://www.kegel.net/patternlibrary/default.asp
Besides a big difference in oil ratio, outside of 10 on a THS is very light on oil compared to the USBC Open pattern. A THS creates a bumper affect by having the outsides dry and a flood of oil in the center. On a THS if you miss to the outside the ball will come back, if you miss to the inside, the ball will hold.
If you try and play the USBC Open pattern to far outside, the ball won't come back unless you have a ton of hand. Having more oil outside of 10 with a small ratio as I mentioned, could also create a reverse block like condition once the pattern breaks down from reactives being thrown inside of 10.
On fresh, I personally would try and play this pattern up the 8 board and adjust from there especially as it broke down. As already mentioned accuracy would have to be within a board or 2 plus speed/rev consistancy is also a factor. If I walked away with a 600+ series on this pattern I would be happy.
