I am considering buying a set of interchangeable needles but I am still unsure about which set I want to choose. I instantly decided against the Boye Needlemaster set since I started knitting on Boye aluminum needles and really don't like them, I also decided against the KP Options Nickel set since I just don't like metal needles and I have a nickel allergy. This leaves me thinking the Denise set or the KP Harmony Options might be the way to go. I'm a bit worried about the KP Harmony as they are still quite new, the set is pretty skimpy in comparison to the Denise set, and for the money you spend on it they give you a crappy plastic pouch to store them in, (might as well just throw them in a Wal-Mart bag). The other thing that scares me is that reviews written about the KP sets are always fabulous, glowing reviews that are conversely dotted with observations I would consider quite negative, (e.g. cables constantly coming unscrewed, cables getting screwed so tightly into the join that they can't be removed without snapping the needles, needles just snapping), oddly I never hear anything of this sort about the Denise set, though somehow it seems like the Denise set is less trendy and therefore has a more quiet following. Any input, pro's-con's etc. from owners of either of these sets would be much appreciated. I'm at the point that I'm thinking it would be best to order a single set of tips and one cable from each set so I can try them out first.
