Jim, the original spey rods were used on big rivers in Scotland with the idea of being able to cover more water with less effort. The casting methods they use are not the same ones used here, I've had a couple of lessons, and was told that "you Americans are just doing a roll cast with it, that's not the point" I believe the ability to mend ones line is also important especially where the rod is used to fish for Atlantic Salmon. That said, you bought the rods, you own them and I'd challenge anyone to tell you that you can't use it anyway you wish.
So there.
Hugs,
