I too checked out some of Jurij Shumakov's fly designs and it inspired me to get onto the vice and tie up some new patterns for the spring. As always I used the style and proportions but created my own patterns based on other patterns and experience.
I found Icelandic sheep to be very good for winging, and also a synthetic called polar fibre. Most of the patterns I've been tying use a combination of these two and arctic fox. I did look at the arctic runner but it is very expensive in the UK. I'll keep looking for other good substitutes.
