Sounds good. Yea the shaped polys + gut is something I don't quite fully understand. I've seen some people say use only smooth polys and then other people are swearing by ALU Power Rough and other shaped polys. Guess it does ultimately come down to personal preference though!You are welcome! To me, Irukandji is the ultimate cross string, specially with Multi or Nat Gut in the Mains. It also works great with another poly in the mains.
If you have another poly in the mains, I will then also suggest to try Liquid Neon Dust (available in half-reels now) or Excellent Purple (available in sets and reels) in the Crosses. The square profile models would not be my first choice to use as a Cross.
In the end it is all personal preference, and I would give a couple of different set-ups a try!

You also mentioned that the White and Blue Irukandji play differently. Could you maybe give some details on the differences?
