Been rebuilding my kanger coils for a few weeks now, and, even though I try to be careful when I'm snipping the wire ends, I'm noticing a few of my insulators have a few nicks in them.  Lightningvapes has insulators, but in both rubber and silicone.  Does one material seem to be better over another?  Price is the same for either.  My smok Aro's appear to have rubber insulators, the kanger heads appear to be silicone.
