Pulled the trigger today @ Sam's Club.

Picked up two 100' Elite POL sets. Questions so I can put my plan to paper... 1) Can I steal a string segment from one set to extend the other set from 6 to 7 strings? Will power supply support that? 2) Each set comes with one 12' extension and two 4' extensions. I know an extension can't exceed 12', but is there a limit on how many extensions can be used in one set? For example, 5 lights strings, each separated by one of the four 4' extensions.

I'm trying to avoid warranty killing splices.
