I just don't succeed in wrapping towel grip up to the cone, somehow I get like very much air beneath it :S. Thanks in advance. Btw, it's for a Voltric 70 and a AT900T
try cutting into the grip a bit, standard is 3cm wide or so, make it 2,5-2cm. I cut from the "bottom" end, but from the "top" should work as well. And try to pull it tight (but don't tear it apart)
I agree with jerby about trimming down the grip a little. I actually trim on both sides so only the middle with the sticky tapes are left. Also helps you work the grip a little more.
