Nowt wrong with the fly mate, have you fished it? I'm interested in how well it floats / stays up.
Not used grey squirrel dubbing, do get a lot of use from some squirrel shit in the Orvis natural fur selection though. Either pine or fox squirrel, can't remember which and the box is on the far side of the room right now.
Not keen on CDC except in very specific applications where I want an ultra soft landing on the water, it irritates me having to change fly after every fish. Looking forward to trying that CDC oil next season.
Cheers
