hi, in a general way up eye hooks for dries( to help keep a little line by the hook off the water) and down eyed for wets nymphs and lures, the length of shank depends upon what fly you're tying but things are a changing. i wouldn't go for long shank, medium and short will do for most flies, light wire ones for dries and emergers and cdc to cut down weight, barb or barbless is individual and if adding a gold head then a good steady bend on the hook is needed as some hooks won't accept too smaller gold heads due to the sharpness of the bend, all in all keep looking/ listening and tying, all the best, bob
