After the "wow" starting because yes these quick clamps are very well built and of excellent invoice, I find myself often make conventional screw instead because:
- They are far lighter than those fast
- They slip to places where the rapids are unusable (the tilting of the handle needs to have plenty of clearance to tighten / loosen)
- Any difference in speed
- No difference for hand tightening to 1 (in both cases this is actually quite galley)
If it all over again I would not take that screw models, much cheaper and ultimately I prefer to use.
