As has been previously posted and recently proven by myself , regular fly line does not at all work well on a 13' 8/9wt two-handed spey rod. That being said, I am now (with humility) asking for advice on a proper weight line for said rod. I have noted in previous postings that The Rio Windcutter multi-tip line is the favored brand. I have found the wt sizes to be in 7/8/9 and 8/9/10.would I be better off with the lighter or heavier of the two? Also if anyone has a used line that that can be used in this initial foray into the realm of spey casting (for sale "cheap")it would be greatly appreciated. The idea of learning on a line costing about 150 dollars in somewhat daunting. Thanks all. The rod is built from a Rainshadow 4 pc blank and rated at 8/9 wt.
