you could do that...I would probably go with 3ft of 25 lb and a 2x tippet maybe 2 ft long. typically thats the basic setup I use. no need to pay four bucks for a streamer leader...the other option would be to save your beat up dry fly leaders cut them down to 3 or 4 ft. and add a little 2 or 3 x to the end of it.
