Joe,

The ones I caught (very small sample size) in Montana and Alaska stillwater's were on softhackles like this (with and without a bead head)









Tried for them on some little blue lines in SW Montana with dries I found on some U.K. sites; couldn't find any grayling looking up that trip but brook trout ate them.

Like I said, my sample size is very small, but from what I can tell, they're not real picky.

Scott
