That 10W30 grade is a natural winner, if you don't need that cold starting below 0F (-20 C), then it naturally makes a low volatility oil. Formulate it to be a little on the thick side and you get a good strong 30 grade that would work for most people.
In Australia our Magnatec 10W30 is even thicker (KV100 = 12.4) and it's rated SN and A3/B4, I've used it and found it to be a very smooth oil.
For those that value Noak above all else (everyone has their preferences), this oil is a winner at under $20 USD. I haven't seen it for some time around here.
