It's nice that you can pick almost any color and weight of disc's that you want when you go there. It's not a huge store, but they have a huge selection because they also do mail order/internet sales.
Me personally I've only been playing a few months and I've bought both online and down at Disc Golf World. I'd probably buy exclusively from DGW if it where more convienient for me to go there. But if you are in the Downtown area or have the time drive down there check them out.
I'm going tomorrow to get my Skillshot!
PS: Where you from? Do you play in any of the leagues?
