Talk Cowan to me.
Look, this is not news to anyone, even me with my not-quite recon path. I pretty much gave him the "Yeah, I don't really work with crazy uncle Iolo's stuff either," line, but then asked him about why he works Cowan's stuff if he's concerned about historicity.
I haven't heard back from him yet, but given that I haven't read any Cowan (because of his rep), I was wondering if anyone could share with me some of the criticism about his work? I'll obviously be doing some of my own research as well, but this community is such an excellent resource I figured asking would be a good way to jump-start my process of actually knowing what I'm talking about a bit more effectively.
