Which oil for nc30

[Neosophist]

whats peoples thought on motul oil, there are quite a few specs to them....

3100
5100
7100
5000 etc

they dont all say either if there are part syn or full.....

I use Motul oil because it is what my bike shop stocks and I get a good deal!

I'm not sure on a couple of those but:

5000- Semi Synth.
7100 - Full Synth.
300v - Full Synth. The dogs danglies but $$. Interestingly, I had a conversation with Mike N and this is what he highly recommended for my tuned race motor. He said it is great stuff but expensive.

Actually, I have an oil question for the masses. When running an engine in, for the initial run in, would you recommend using mineral oil or semi-synth? I seem to remember, for the initial break-in it was recommended to run mineral and then change it out fairly soon?

I have a friend uses 300v in his hrc spec track 30, says it's good, especially on really hot days
