I actually just got a couple 2oz bricks today by calling a gymnastics club, and they were able to direct me to a place that does sell chalk that was right nearby.
Might try giving one a call if there is one by you.
I am going to do just that tomorrow for back day. I will let you know if I find any differences between the two.
Oh yeah, I saw that rosin bags are also sold at some places that sell baseball equipment. FYI.
Did you check on-line somewhere? Might be cheaper, too.
good news, my local mountain climbing shop sells em!
They're out of stock of chalk blocks, but they have chalk balls - I guess you rub yout hand on it. So that will tide me in for now, gonna set that DL PR tommorrow!
