Sandfly,
Has point on. if you tie streamers Featherwing{rangeley style} Marabou wings,or bucktails sparse is the way to tie em or to buy em.Hey IHRT, on your way into Maine if you come in off 95 or rt #1 theres a lil town called Kittery,look for the Kittery Trading Post go down stairs the fishing Fly,and conventional tackle is all down there,if you go further north stop at Freeport at LL Bean look for the hunting/fishing buildingthey will have some flies too.
If i were you and you weren't gonna tie,Call Sandfly and have some tied up for you he ties a great fly and has done the pond thing, I can only speak of streamers fished in the rivers and creeks up there TroutSpey or Singlehanders.I do know if you fish rivers better off getting a sinking leader loop it to end of your fly line and 2 1/2' of flouro tippet and yer set.
Presentations that work on rivers will be standard swing down and across with a hangdown at the end, also cast upstream and stripped back will get your arm ripped out of its sockets when they take this is Galloup style.I also like a whisker up and across like yer nymphing and and then dead drifted when it gets close to end of drift before the swing i strip the fly alot of takes on that retrieve.
In ponds and lakes things will be fished a bit different using a different line system and possibly a countdown for finding depth.I dont know the current rules on split shot up there either thats why i use a few different sink rated sinking leaders.
