This is a matching headband to go with the Mohair Irish Hiking Scarf that I just finished. When I switched over to the Options, the first thing that got my attention was how that it suddenly didn't feel like I was knitting with a "fuzzy" yarn. Each row was smooth and since I am a Contential knitter now, it felt like my speed had increased a little. Then I laid it out and seen that after about 4 inches of knitting with the new needles I could see that the stitches were even and more uniformed and the cables laid nicely. So switching to the Options gave me much better results. Those sharp little points on the Options became my best friend when it came to working with Mohair.
So it's my personal and humble opinion, that theses are wonderful needles. I don't think that there is a yarn that would not knit up nicely with these. I like the case and all that comes with it. The needles connect smoothly to the cables and they don't come undone while knitting. The are so smooth, that the mohair never caught one time. They are pointy so if you don't like fairly sharp points these aren't for you. I am so pleased with these needles that I'm going to purchase the size 1 and 2 circulars for socks, and get another pair of US 5 and 9 with more cables to round out my knitting needle needs after that, my needle buying days are over and I'll spend that money on yarn and coffee. LOL.
