OK, so I'm debating the use of DL's on a design. I have basically a large background that I'd like to put content on, so I was thinking about splitting it into top and bottom. The top throw is around 15', the bottom around 19'. Thus, I was thinking collaging DL's to allow me the ability to create on large background. They would have the same lens, but obviously massive keystone correction on the lower fixtures, and less on the upper. Would doing something like that be overly difficult? I know there's a lot of correction built in, but never having done a large collage I'm more apprehensive.
Also, I may have to mix lenses between the throws...that concerns me even further.
