Canare 4S11 user here too, and with the estimated over 400 hrs burn-in, not terribly excited about going through the same thing with the G.
I still recommend 500 hours, (Canare recommends 200, but it needs more). I totally understand your thoughts about break-in. I have a separate system that I use strictly for cable break-in, so it will go into that system for 21 days. No harm , no foul...
