When we talk about ripping tartan, we actually mean we cut about 4" or so into the edge with scissors, then take a good handful and RIP it , usually in mid air!, then we take a newer hand ful close to end of where we have ripped , and then RIP again. It's scary the first time, and it does take a bit of confidence, but it really is often the best way.
I've only use PV a few times, yes it rips ok, but I suspect I'd be tempted to cut it or scissor rip.
