Re: podlock: polymer vs zinc
The Pod Lock is a great design. But it is a handle that sticks out and can get bumped or snagged.
The advantage of the polymer is that it is meant to break, rather than something else break. With the zinc, it is much tougher and you can risk breaking something expensive, rather than the $20 pod lock.
Terry had it right from the get go. The polymer handle is meant to give way before anything else.
Get the glass reinforced polymer.
