Has anyone here used both the Elichrom .... Deep Throat and the 74" Octa-bank deep lighting system? If so can you give me a difference in what you've found.... Pros and Cons... There is about an 800$ delta but I'm being loaned these from a special friend and would like to ask for only one. I'll be in the studio shooting very tasteful nudes. I'll have an assist. to help moving. Also, I think the 54"(?) does not need a C-Stand where the 74" will (I've used this before) I know the 74" light really wraps around the suject so softly. Does the 54" deep throat? Also, the Ranger RX system driving these????? Any help would be very welcomed.
