My go-to fly for spring is almsot identical to this pattern. I use Arctic Fox or rabbit for the tail and a bubbing brush made from seal fur for the body. This pattern is extremely effective for both trout and warm water and almost indestructible when made with a bubbing brush with wire. I've had many of them last well over 100 fish and still be going strong.

It may seem like a lot of work and specialized "stuff" but I can tie these with a dubbing brush in about 3 minutes and if I could only take one pattern it would be this leech tied in size ten and six.
