Wondering why

I have finally written a long explanation of why one wheel trailers are better than two wheeled trailers for motorcycles. I'd love to get your reply!why one wheel v.s two wheels that is more stable and will carry the weight better. I can just imagine the tongue weight of this compared to the 2 wheel option, what happens when you lean taking a turn how does the lean of the single wheel react on the bike or is it independent of the towing vehicle. I find the ball type tow mechanism much more robust and time tested and have seen many long-haul folks use it. Need to the advantages and disadvantages of a single wheel design...
Looks very cool and interesting, but need to know an in-depth analysis of all the forces involved in a single line wheel system.
