So here are the blades that I own. The two Darker 5P-2A are my main blades. Those are my absolute favourites, I love the touch when I play with them....
Would have been interesting how heavy their testing blades were. Clipper blades vary a lot in weight. A clubmate has one which weighs 85 gramms, mine...
Maybe a bit off topic, but I remember in the early 90s I played with a Donic hybrid rubber called "Shangri La". The topsheet was just as tacky as any...
