The Pingle is pretty but has no performance value. I hear it operates smoother but I have heard of some having problems with getting it to seal against the tank, leaking the first couple tries. My stock valve sticks sometimes but doesn't leak so I'll leave it alone until it needs to be changed.

I learned all I need to know about life by killing smart people and eating their brains.
