Hi everyone. I have heard lots on these forums about the provided shifter and cables being poorly designed.
I just installed my shifter and it has so much slack in the cables that when you are in any gear, the shifter will return back to center, and when you look down you can't tell what gear you are in.

Here's a video showing the slack:

In addition the effort required to shift is very high.

I can't imagine that this is the way the shifter was intended to function.
Anyone have any ideas?
