So should I be using the pre-mixed fuel from stihl in my stuff? I bought the 2 cycle oil when I bought my stuff just to get the free 2 year warranty but they filled everything with the pre-mix when I bought them.

much of the premium stuff has very little ethanol in it

It's not just ethanol. Eventually the surface of most plastics will change enough due to lose their plasticity and will break apart. Gas also loses is volatiles and gums up lines. It happens a lot more with cheap plastics from China. There was a big problem with Yamaha boat engines in the late 90's where they added a liner to fuel lines to combat the ethanol in the gas, but they were cheap shit from China and lots of the liners dissolved over time and gummed up the engines.
