Trout,
I can't recommend anything Scandi or Skagit.I use a Rio Windcutter Spey on both my spey rods, i use a 4/5,and a 5/6 on my Gloomis streamdance Metolius Troutspey 13'4" 5/6 wt,and I will use a Rio Windcutter Spey 7/8/9 spey as well as a Wulff Triangle Taper Spey on a Scott G series 14' 9 wt.
I have to find a bigger reel for the Scott yet.BTW thses are full floating lines ...no heads. If i need to get down i use Airflo Polyleaders,or Rio Spey Versa Leaders. I also use poly leaders on my Trout Spey.
You will need a Golden Pheasant skin, Mallard flank,Bronze mallard flank, Wood Duck Flank, Blue Eared Pheasant {BEP} feathers sized to the hook you are using,Schlappen comes in a bunch of colors,Turkey Center Tail Feathers,maybe some goose shoudler for colorful wings ect.
Tight Wraps & Tight Lines

Opps i almost forgot, Angora Goat ,SLF ,STS Trilobal,Lite Brite,Prism,UV dubbings all are great attention getters.You will need some spools of various tinsels,flat and round silver & gold embossed,Mylar tinsel in a few different widths.
Maybe some floss in various colors too the possibilities are endless like the Stars in the Sky.
wire also in various colors to suit your fancy so you can secure the hackle,yea you can use tinsel too but tinsel and wire makes for a highly durable fly.
