What the heck is a single handed spey rod? I assumed that a spey rod would automatically mean it was two handed. But Cabela's sells a single hand 11'3" 6 weight. Is that just a marketing gimic for a super long 6 wt? Or does a spey rod have more to do with the type of line it throws than then hardware configuration. I am not really interested in purchasing it, I was just perplexed when I saw it. My whole spey rod paradigm is being challenged by it's mere existance.
