I've tried a few different strings on my Bronco, but I've been pretty happy with the ECB81S Chrome set.
The short scale keeps the tension down. They feel and play pretty good.
BTW, if you decide to go for a two pickup setup, it's pretty straight forward. Just put in a side jack, route out a space and cut the pickguard.
This will leave you three holes for a VVT setup.
