Hmm, interesting issue indeed. I shoot with 28-70L for almost year a half already (it imemdiately became my main lens followed by 70-200/2.8L), so far had never experienced any prominent flare even in potentially flare-prone invironmental shooting. However I had never ran any tests shining directly into the lens specifically to reveal it's flare resistance. I also always use its hood and it is fitted with Hoya Super HMC UV[0] filter on permanent basis, so far no specific issues with flare.
Perhaps I can burn out a few frames specifically to test that soon, (I plan certain environmental session) to check it out...
