i have a #7/8 floating head with float/hover and int/s2 tips and the grey (thinnest) running line and I like it. I think it gives a bit more delicate presentation than the similar weight Rio Scandi Short I use on the same rod.
I’d check that you can get the tips you want before committing to buy one.
I use a 8/9 set on my Hardy Zephrus 13'6 8/9. It works very well. In fact - I bought the "whole range" in 8/9 when on sale ! So I am happy with it. On that rod - I have only found 1 other line working that well to me.
