Multi Pars

I'm about to use multiPAR strip lights for the first time on a cyc that is 30 feet high.  I'm curious what experiences people have had trying to get as even a field from top to bottom.

Some questions:  whats the optimum distance from the units to the cyc, is closer better or does distance help?

Beam angle, MFL, WFL, VWFL?

 

Any info appreciated.

Thanks

Stephen
