I've used that pattern a lot this past season - the hurl holds up pretty well for the abuse/use I've given mine. It's an easy fix too, if you want to repair/replace damaged stuff.
good looking bugs BTW
Be sparce with the yellow - it can overpower the fly quickly. I've used fluorescent green & blue in some of my variants, they too can overpower. I like to top it off with olive & hurl no matter what colors I use on the rest.
good luck with 'em
