fishfirst, You may mistakenly be conflating a couple of things here. When “switch” rods first came out they were marketed as rods you could cast overhead AND two-handed, and because of that gimmick many to most of these rods were a little faster and tippier that some spey rods - faster and tippier being more like current trends in single hand rods. All those long-time single hand fishermen who finally got up the nerve to get one figured out in the meantime that overhead casts with these rods were special cases and hardly ever did them.
Nowadays, especially in the last few years most switch rods are produced with a deeper flexing action more characteristic of a traditional spey rod, and arguably more useful for (certain styles of) spey casting, and you seldom hear people talk about how great they are to use both ways - not even salesmen. They are just short spey rods. That said, there are still some tippier “switch” rods made, but many of these, at least in NA, are now specifically targeted at people who intend to use them primarily or exclusively overhead, as with surf fishing, etc.
But as bender said above, there is no such thing as a “switch taper”. It is the added LENGTH of a spey rod, and the more relaxed tempo and margin of error that can make it easier to learn, not necessarily the taper. A deeper flexing taper on a spey rod can also make it a little easier to learn IMO, at least initially, but there are many spey rods with very fast, tippy tapers, and many people who love them.
So the real question related to all this is which specific switch rod do you have, and which spey rod are you thinking of trying, because there are ALL types of taper available for either length. If you just want something deeper flexing but in a switch rod maybe take a look at the TFO
Deer Creek switch rods. But you should definitely take the plunge and try a spey rod regardless!
