Cannot name it - it's just a locally produced rubber glue that everybody here used for years - and most still do (last item on the website
http://www.ping.home.pl/index.php?cat_i ... rt=default), indeed a very good one and not damaging the blades.
The water glue is "MODEST Clean VOC". Modest is a big TT shop in Poland, they have their own trademark, the glue itself is made in Germany, by a producer that supplies all other German brands.
Both glues perfectly work with other rubbers, inverted or pimpled, so the problem with M1 is certainly not caused by the glue.
I also think the problem is not in my own play, I'm a rather experienced player, and anyway the inconsistency problems disappeared immediately when I returned to S1, I also had no such problems in the past with Ternergies of Hexer HD, or even other rubbers that I've been playing with last year like Boost TS or Haifu Whale II.
And I can frankly say - I was the first and only one in my environmenty to try it for so long, none of my friends who tried it even considered a purchase.
