It might surprise you to know that I reached for my Denises over my Addi set that I've had for (!) Nearly 4 years. I'm knitting the baby jiffy sweater (I have a thread in Whatcha Knittin') that has the most absurd amount of increases and decreases in one project that I've ever done. M1, KFB, K2TG etc. No problems. Knitting with Gloss DK, too.
