Pretty sweet tie Clint.. I have had good luck with a contrast shellback color stone many many times.. I'm not sure if it's specific color however..
All my shu blue flys have been an egg variation.. Be it single, sucker or double sperm..
Actually I was feeling pretty blue all day after stepping out in the field of work.. Crazy people who have no clue or care..
So glad I don't actually own the equipment
..
Now if I only was so lucky to have binders full of women that wanted to tie all my flies too..
Instead it's just me and BB tying tonight, maybe a little Marley thrown in..
