Do your hardy kiwi varieties all bloom at the same time?

This is a follow-up to my question about Issai fruit set. If you have multiple varieties of hardy (arguta) kiwis, do they all bloom about the same time or how different are they in bloom time? Does anyone find that different males bloom earlier or later and therefore do a better job of pollinating particular varieties? Does anyone have more than one variety of male specifically in order to cover different bloom times?

My argutas would bloom fairly close in time, I have two males but only one would do it. The fuzzies on the other hand are very spread out, I have three males and really need them.
