I was looking at a different thread and this thread popped up in the "related posts" at the bottom of the page. First let me say I strongly suggest you use spey lines and spey lines only on spey rods. Over lining 3 weights is a statement that has popped up a few times. I don't know how this kind of stuff gets started but in my opinion is not only wrong but explitive deleted wrong.
First the spey rod thing. Spey rods all have a grain window. The amount of weight, top and bottom end the rod works best with. This grain window should be followed like it was handed down from Moses carved in stone. Regardless of the type of line used and it should always be a spey line.
Second the grain window rule applies to switch rods as well. You can use a traditional single hand line or a spey line as long as the lines falls in the grain window for the rod. You will like a spey line better, and second best, key word being second, is a traditional line with a longer than the normal 30' shooting head. On this type of line if the head and the running line are not different colors, you will need to mark where the head/running line junction is.
Third, overlining a single hand rod by three weight is just not a good idea. Even if you needed to overline three weights to make it work, why would you wreck the overhead casting ability of the rod to do a type of cast that face it, if you were going to do it all the time why not just get a spey rod. However. You do not need to overline the rod AT ALL. If you want to spey cast with a single hand rod, just mark where the head/Running Line junction is and because you need to have the head out of the rod to do these casts or at least very close to all the way out. The best lines for doing spey casts on a single hand rod are lines like the Trevor Morgan line. It has a green running line and a white head that is 43 1/2' long on the 7 wt. line. The last time this came up, I made a video to show just how wrong the idea you need to overline by 3 weights to do this is. I used a single hand 8 weight rod and the Trevor Morgan 7 weight line. So I am underlined by a full weight. 9' leader, plus the 9 foot on rod, plus the 43 1/2' of shooting head puts the fly 61 1/2' -10% for squiggles = about 60' away just rolling the head out. Shoot another 10 or 15' of running line and, well you get the idea. Once you get used to the rod and the line you should be able to shoot 20' of running line fairly easily. Here is video. Four line weights under what people keep saying you need.
The only reason I revived this old dead thread is because someone, like it happened to me, may see this pop up one day in the Similar Threads thing at the bottom. I'd hate to see someone go and buy a line 3 weights to heavy for the rod they own only to find out later at the cost of $??? just how wrong this notion is. Randy was just asking the question here but it has popped up in other spots where it was a statement and not a question. Nobody in this thread involved.

I agree, a more moderate rod will spey cast better. The rod I was using in this video is a pretty fast action rod. The long bellied lines is right on. Another good one is the AirFlo 40+ Expert. It's head is 44'
