Dry fly hackle - best face forward?

[ScottP]

I tie both in dry fly fashion. Dull side forward.

Ralph's response in his Bivisible Moose thread got me wondering. I've always tied my hackle shiny side forward, whether winding collars, palmering bodies front-to-back or back-to-front (for parachutes it's shiny side down). I know at one time it was pretty common to tie dull-side forward, before the advent of the genetic hackle we have available today. I was wondering which direction other folks are going these days on their drys?
Ralph, in no way am I criticizing your choice; it's obvious from the vid and photos that you're producing a quality fly.

Regards,
Scott
