I think this a subject that is important for new Handi owners and bears repeating. New Handi owners are more likely to be too gentle in closing their Handi's and the result will be vertical stringing. The test of a properly closed Handi is the force required on the button to open it. There should be a definite crisp resistance required to open it. This is especially important on new Handi's and may be harder to achieve until the latch and lug shake-down a bit and mate up properly in their final positions relative to each other.
