Poly/Multi is a very good alternative to full poly if you like poly but want a softer string bed.
On a side note of the conversation I actually found a use for Power Fiber II outside of throwing them away. It plays very nicely as a cross for a poly. I crossed it with PLII in the mains in a blade 18X20 at 54/57 last night (out of boredom). I was very pleased with the results. They actually slide well on the poly, give good comfort, while adding some easy power.
