I am fairly new to the spey game as well and i had the same questions when i was getting started. There's lots of good info in this section about this topic, it's been discussed on here before. I am no expert on the subject, but i can give you my point of view since i own both a switch and a spey rod. If i was strictly going out swinging streamers, a spey is the way to go. It has the power to pull the flies out of the water with ease. I can do it with my switch but it is a little more work and i do not get the distance or control i would with the spey. If i was going to spend a day high sticking nymphs, i would use my switch on the basis of weight alone. The spey rod is much heavier and i think my arm would tire if i used it to high stick any great length of time. Its tough to say which one is better, they both serve there purpose. Most days when i head out, i will pack both in the truck, but 9 times out of 10 its the switch rod i rig up and take to the river. It's more well rounded for me, and it gives me the option to do a little of everything. If i was to head to BC to fish for salmon, the spey would be the only way. My little switcher would be far to light to handle those brutes. I hope this helps.
