LA was about 1- 1.5 seconds faster for me than Hellyer on average for a kilo. It's not known as a particularly fast 250, but I think it's still faster than most US outdoor tracks. But going there with low/no expectations is the best way to have fun! It can be a cool experience, and for sure your first time on a 45˚ wood track is unforgettable. If you can, try to get there a couple of days early to get some less high-pressure time on the track. If you're used to a low-banked 333 it's a pretty huge adjustment.
