Thank you for kind words Stone NY! Also for good tip for labelling cassettes. As for Maco films, photographer from Finland, who pushed me in the direction to use 70mm film with Hasselblad, Jukka Watanen, http://www.flickr.com/photos/40146285@N08/ is their official dealer. So far I didn't order any films from them thru Jukka or directly. I was lucky to buy 70mm processing reel as old stock in local camera store. Next time I'm in their neighbourhood will check do they have any more of them left.
As somebody raised on Paterson reels, I found loading this metal 70mm reel not that challenging. Not more than any other 35 or 120 metal reel. As soon as I have secured beginning of the roll, rest of loading is easy.
StoneNY, what kind of reel are you using?
Well, keep shooting Guys!
