I switched over to QD a few years ago mostly for long lens setups and haven't looked back. However, for my monopods I ended up rigging a velcro strap with QD connector and swapped it back and forth depending on which monopod I was using. These QD clasps are a much better permanent solution, and the two sizes I purchased fit both (non-Leofoto) monopods perfectly and seem to be very high quality. Very happy customer.
