I heard second hand that they put a lot more oil out this year than previous years, with some sort of OOB.
My experience has always been not that they don't put out oil, but it doesn't seem to last very long. The fresh is actually pretty nice, but it tends to break down fast. The re-oil they do in the middle of the day helps for about 5 frames. The one thing I've always noticed over the years is the lack of pin action. I don't know if they have old pins, or the sidewalls aren't friendly or what, but I always see a lot of strange leaves. Lots of 9-10s and other oddities on decent pocket hits.
