I'd be careful firing Yongnuos at full blast at a rapid pace. I burned out my first 3 YN-460 II's doing that. Heck, not even full pops burned them out!
I did eventually enjoy using my YN 460 II's for white a while after I learned to back off on the pace. I now have YN-560 III's and enjoy those as well. I know they're supposed to have more advanced thermal management, but I still don't trust them.
Just my $0.02
