I have noticed the lack of a quick-turn knob for the wooden leg screws, but on the aluminum legs I could never get the knob on the aluminum legs tight enough to keep them from slipping. Very frustrating.
Furthermore, the original tripod legs, like most tripods, but unlike the wooden set, have a simple knob to turn for shortening or extending the legs, allowing a quick length change with a single hand, while the wood replacements have 2 simple screws with wing nuts on each leg making a length change in the legs a pain and requiring 2 hands, one on each side of the leg done twice for each leg. They are now sitting unused in my garage.
Neither are perfect, that's for sure. The II with the ability to put it on a real tripod is a big improvement.
