Burley trailer hitch, classic or alternative? I've just bought a new bike that I intend to tow my Burley trailer. I've always used a standard hitch before but this will not fit on this bike because of the way the rear drop out is made.

I gather my options are the alternative hitch and the classic hitch.

The alternative hitch looks ideal.  However, I can't appear to get hold of one in the UK.  It looks like it might be discontinued.  Does anyone know if that is the case?

As for the classic hitch, I'm reasonably convinced that it will fit. However, I'm unsure how quick and easy it will be to disconnect and connect the trailer. My daily routine, storage space etc. means that I need to do this once a day.  So my question concerning the classic hitch is, how long does it take to remove and reconnect the trailer?
I had one of these that had, at the end of the towing arm from the trailer, a moulded plastic part that fit in the angle between the seat stay and chain stay tubes, it then had a hinged part that was tightened down onto the seat stay. It only took 30 seconds to fit or remove. Having said all this I do not know if this it the 'classic' or 'alternative' system.
