The best set of phosphor bronze acoustic 9s that I've used. Worked great on an electro acoustic and were fab for conditioning my electric fingers to the ways of an acoustic, without a big jump up in string gauge. For me, they (and other Rotosound acoustic sets) have a more balanced feel of gauges and tensions across the set and they stay fresh sounding for longer than other brands of phosphor bronze strings that I've used.
If you're looking for a relatively inexpensive, light gauge set of phosphor bronze strings, these could be just the ticket.
