Yes, many of Jurij's designs are more than worthy for Steelies - some were actually developed from NW patterns!
I've a small assortment of his tubes - they are, as you'd mentioned very similar to the Loop design.
The most unusal or exotic materials he uses are some of the furs in his hair-winged designs. (Arctic Runner is a somewhat acceptable substitute for some of them.)
If you have specific questions on how to purchase some of his proprietary tying materials, just drop me a PM, and I'll pass your e-mail address to him.
