That's pretty dumb. They are available on the shelf (in Aus). Why wouldn't they release them in a similar time frame in the U.S.? I'll stick with the Cally CS since I got a big stack. I was just interested if anyone had tried them. I'm not buying a box because I have 6 doz CS @ $27, compared to the current price of $49 for the duo urethane (FG tours are $39) so it'd want to be good.
Remember that Australia is just beginning their season now (it's Spring there), while a lot of the Northern Hemisphere is entering late fall and winter weather. Do you want to release a ball at a time when few people are playing?
