Blisters suck. Yesterday I had a little blister underneath a callous that popped. It made tricks class a lot harder. It did force me to work on tricks on my non dominate side. I even got a video of me doing the monkey on my left side. That will be up at the end of the month with everyones money combos.
I need to work on what to do with my hand. In the video you can tell I am not sure where to put it.
