Here's a very promising review from Amazon (although we don't know which gauge):
"Ok... I have been a flatwound player for a looong time. I've used EB, D'add, La Bella, Thomastik... but these are something else. I've never played a flatwound string that felt like this. The smoothness is perfectly glassy. It's honestly hard to describe. The tone is perfect - They sound vintage, warm, creamy - I absolutely get why these are Pino's signature sets. But seriously.... the feel is incomparable."
