@Caliban - I just stripped my Ti down after a similar period and other than some particles at the top of the stem it was cleaner than it should have been, no severe stickyness, it gets a lot of use.
Could perhaps be the result of a less complex airpath and improved cooling that moves vapour faster ... ?
I'm not 100% sure what it could be, but I also thought it must be the simpler path or maybe the vapor is warmer and not cooling as quick? I mainly used my T1 with the WPA adaptor (and know very little about the science of vaping), so maybe not the best person to compare. But I had to clean the set up weekly and the adaptor was always getting stuck to the head's o-rings because of all the resin. Maybe my adaptor was rubbish or it was user error?
