I just used Bear Paws yesterday for the first time. I have to admit that it was pretty fun shredding up those 2 butts. I felt like a bear digging for truffles.
One thing about the Pork Puller. My buddy has one and it kind of shreds the pork instead of pulling it. Don't get me wrong, its still a lot of fun to use, but it's not for everyone. He stopped using it because it was just about as easy to just shred it with tongs in the pan and made less of a mess. The other part is that you have to move it to a bucket to shred and it gets all those good juices all over the bucket instead of in the pan with the pork.
Ben, if you were going to modify, maybe finding a way to not over shred the meat would be good.
