Hi Jim,
For ease of installation I rekon you cant go past the triumph/bsa conical rear hub, it will sit perfectly within the 7" swing arm. Yes it may be a little heavier than a CZ etc hub but much easier to find here in oz. I ran one of these in my Triumph 650 metisse last year in the Heaven rounds.
A set of CZ hubs fortunately landed in my lap over the off season which are now fitted, I must say, they look much nicer!!!!!
