I did a general check of my photo's: the most flare I get from the Sigma 20 mm (nice halo's) and Samyang 14mm at f/2.8 (big burst that covers half the frame). Neither of these flares may be sufficient for you though. The 100-400L gets ugly purple/green crosses when car lights shine directly into it on the race track. It must be said I'm generally impressed with the resistance to flare of most of my lenses.
