So gaff is a firm believer in the McCandless method, nothing wrong there. Depending on
FOH positioning and beam angles it may be simpler and more effective to just have a flat front light wash. Your frontlight wash may extend onto your over-stage electrics to light the US areas.
Charc, sometimes I wonder how much info from here makes it in your head. How many posts have you read about how the FEL is not an ideal lamp. I am sure that Ship has posted 10+ posts about better lamps than the FEL. You should search them out, and then stop using FELs in your lights. Also, a S4 Jr. can't be lamped at 750w, so that idea is out.
Effectively utilizing your S4 Jrs. is hard to speculate on without knowing the beam angle. But in a way it is somewhat 6-in-1 half dozen in the other on account of if you only have wide angle units you may need to double up to get the intensity you need, but if you only have narrow units you may need more to get the coverage you need. I would take the S4 PARs and arrange them evenly with 4 on the 1st and 3 on the second and third electrics. Use the PAR64s as side light pipe ends (I think mentioned above), 3 on each side of the first and second, and 2 on each side of the third elec. As for the PARNels, use them to fill where needed, but personally I would find some sucker would will trade for S4 PARs, or just sell them and buy a real fixture.
I have to imagine that the "
cyc" lights you have are more like strip lights, MR-16 or R-40. Otherwise, it seems highly illogical to hang cyc lights on the first
electric, probably the farthest from a cyc. If you really have strips and not cyc's this will help with your top light, and could allow you to spread your s4 PARs to other locations.
