Hi! I am currently using a Bluefire M1 on my fh. I want a slightly slower and spinnier rubber. I was thinking about the Donic Bluegrip C2 and the Tibhar Hybrid K3, but I heard they are very difficult to use. I was also thinking about the Tibhar Genius... So if you could please either compare the rubbers above to the M1 or recommend me other rubbers, I would be really happy.
