I bought the V1s a few years ago, and loved them. Bought the V2s to see if there would be an improvement - I was a bit hesitant based on a couple of reviews that said the cut-outs pinched them. Thankfully, that wasn't my experience - the V2s are very comfortable to play in, and I appreciate the cut-outs so the back of my knees get some ventilation. Plus the cut-outs make for easier washing - it's easier to flip the pads inside out .
