Though I initially suggested Amsoil, based upon your intended usage:

In all seriousness, any oil you choose would be fine. In fact, I would look at the cheapest oil that meets specification and just change it more often than looking at a uber premium (more expensive) oil which has its strength in extended OCIs.
You're right probably don't need the most expensive oil, just need one fit for purpose. Do you see any issue with the 75w90 given that it's 50% higher viscosity?
