My furled leaders are 5' long and I love them. I think the reason you don't see too many advertised is that they are so inexpensive to make. I love the way they lay out a fly and that they don't have any memory at all when using tying thread. The fact that they are less than 10? each is a BIG plus. I use light colored tying thread for dry flies, and dark thread for wet flies. Actually, I gave two away the day before yesterday, and replaced them with two more today.
