Pleased you like this fly.
It can be tied in many sizes for sure from small regular hooks as a wet fly to large streamer style, in fact it is considered to be one of the best streamer flies for sea trout and works great for salmon.
The fly an also be tied as a multi hook tandem rig, two or 3 hooks
No doubt it is a great fly to represent both pin fry and larger bait fish.
It can be a deadly fly to use late evening into dark.
It is also called the Lady of the Lake and was at one time banned on one famous fishery in the UK, would you believe.
I have use also many variations from the original, here are a few of those.
Body is gold tinsel not silver.
Thorax region is red seal fur.
Hackle red.
Overwing teal ( I posted a pic of this fly last year on TPO)
Jungle cock cheeks.
Mainly l use 10/12/14 regular hooks for my wet fly use.
There is another fly l would suggest you also consider called the Peter Ross.
Davy.
