If you ask me, looking solely at inter string friction misses the point, because there are many other factors involved in determining what would make a good poly. Tension loss, firmness of the string, resistance to going dead would be other key considerations IMO. I'd rather have a poly that is strong in all those areas if its at the slight expense of inter string friction.
I'd also suggest trying 4G as a cross. I've only just started a playtest of that string but on initial impressions, it potentially has some interesting characteristics.
