Probably hard to go wrong with the synthetic Evinrude XD100 2 cycle oil.
I wouldn't use XD100 in a pre-mix situation. I may be wrong, but I don't think it's even TC-W3 rated. Use a quality pre-mix semi synthetic if you want the best available. The X30 would be better suited (BRP suggest XD30 for carbed 2 strokes) but even the wally world supertech oil is really good.
