Dura Ace 7900 Chainring Compatibility

Shimano do not suggest combining A & B chainrings, as it may affect optimal performance. Has anyone got any experience of running a 53 B and 42 A? Tks

This has been talked about on weightweenies before, think the only issue was shifting under load to the big ring not being as crisp
