I've been wondering this for a little bit. It seems that these prepackaged hybrids are more expensive than their companent strings. Take Wilson's Champion's Choice for example. It combines Wilson Natural Gut (although why anybody would want Wilson when they can get VS for the same price I'll never know) with Alu Rough. Champion's Choice is 30 bucks, or two sets for 60, while Wilson NG+Alu Rough puts you at 58. Or take Klip's NG hybrids. It's 26 bucks for legend, plus a a few dollars extra for either their synthetic gut or a basic poly. And yet, they sell the hybrid for 20 bucks. I must be missing something, because I don't understand why some people would want to buy the prepackaged hybrids.
