Sounds like a solid plan. The reason I am going straight to amsoil right away is because engines of today don't need the long break in like they used to. With in the first couple minutes the rings are already fully seated.
Also amsoil has a lot of oils that are high in zinc and phosphorous. The 4 stroke is a group IV true synthetic with no viscosity modifiers and it has a lot of zinc. The base stock is so good they did not need to add viscosity modifiers to make it meet 10W-30 specifications. It is actually a straight 30wt oil that happens to meet the pour points of a 10W-30. That is when you know you have an ultra high quality oil.
