Yeah, read another one like that the other day too. To be honest, when ever I have used the crystal type buckwheat, it doesn't have 'the taste' and does taste like a normal beer. Especially when I have used German hops. But when I roast the malt fairly dry, I get 'the taste'.
I might be adding some flaked millet and some maize to clear as well as some Irish moss, of course. Haha
