How wide a gear range do you require? My (limited) experience with epicyclic hubs is that a 25 percent gear ratio step is far too wide for my tastes. The only one I really liked was my 12-speed hybrid drive train, a Sturmey-Archer 3-speed with a 14-16-18-20 Cyclo cogset conversion kit. A half-step pair of chainrings, say, 42-40, would have made it a perfect 24-speed.
Also, note that the mechanical efficiency, repairability, and long-term reliability of even the best epicyclics cannot match those of a good derailleur-based system.
