but as I learn angles with the Berg, I'm thinking the Pig's days are numbered.
I dabbled with a Berg. Definitely an excellent little approach disc. It wouldn't kick the Pig out of my bag because the Pig will cover distances for me that I couldn't hope to cover with the Berg.
Not to poop in the Berg discussion, but I watched several women using these new, rubbery discs from Divergent Discs for their approaches. Talk about a disc with zero ground play. They almost make a Berg look skippy.
