Yongnuo flashes on Pentax bodies with triggers/cables

I have two yn-460 for small tent box products shots and trigger them with sigma 500 super bounced or reduced to 1/32 pointed to one of them, as they have optical trigger built in. All in manual mode. But K-5 raw is very forgiving and in PP is easy to fix underexposure etc.

I plan to buy radio triggers because in sunny and light environment optical triggers are unreliable.
