Hi Russ,
I do the same as you re oil change interval, I have done that every bike I have ever owned since I was 17. That is what ever the scheduled maintenance duration was for an oil change I change it twice as often.
I have used Motul M/C oil for about 10 years now but mostly because after using all sorts of oils over a 32 yr period I like the slick gear shift the Motul has always given me.
But it is dear as poison. My dealer bought a huge shipment a while back and I got some very cheap but it's just about all used now.
