Da Bean Co.

I'm interested in a strain called Callahan. It's suppose to be Colombian Gold × Herijuana. The seed company is called Da Bean Co and the only place I can find it is at the Royal Canadian Marijuana Collective. There is zero info anywhere on this strain on the web and very limited info at the RCMC website. It sounds like an interesting hybrid I would like to try but would like to hear from someone thats grown it or at least has heard of it and has some info on it.
