Well, I have the OPTIONS NP, Harmony's, and Addi Clicks.
When Z's were launched, I was curious how they would work, you know, the surface...slick or not, grabby or not.
I found that they perform pretty much like Harmony's. They are not as ssssslick as Options NP's and Addi Clicks. They have about the same "grab" as Harmony's. And many times, the Options NP's are too slick for some work...so I use Harmony's.
Between the two, performance wise, they are so similar that I didn't purchase beyond the 3 Z's I have. I bought 6-7-8's, tips only. And left it at that.
If you don't have the Harmony's, you could put the Z's to good use (for a better price than Harmony's come in at!)
However THAT SAID, if money is not a decider...I prefer working with Harmony's.
I like wood much better than acrylic. BTW: I love the Harmony's.
You can't beat the price of the full set Z's. And they are pretty. A good purchase if you think you may only need them once in a while. It's hard to resist the full set, it's such a good buy.
Hope this helps!
BTW, did you see? Addi will soon be launching their Addi-Lace (interchangeable) Clicks! Blue cords, not red. And the set includes 5 cords, not 3. The tips are shorter to accommodate the 16" and 20" cords. Hmmm.
WEBS is taking pre-orders.And their website tells all about them, and gives a link to Knitter's Review on them.
I dunno. KnitPicks OPTIONS kinda "fill the bill" when it comes to sharp points for cable work, lace work, and other tight places.
I've heard that Addi Lace needles stink. That they begin to smell like copper pennies.
I was at our South Sound Knitting Guild monthly meetup last Sunday, and a knitter sitting next to me was working with Addi-Lace set circs with the red cords. I took her needles and gave them a sniff. Yup, they smelled funny, like metal, or copper pennies.
I've read that it might depend on the chemistry of your hands. But I've also read the copper penny comment frequently enough to SHY AWAY from the brass finish of the Addi Lace. Nothin' worse than smelly needles. A real turnoff. And I've heard (read) that the finish of the Addi-Lace can discolor some knitting. Ack. I'll never know if my chemistry is a killer.
