I went with the Versiplug-R on my hull with the idea that if i didn't like it, I could replace it with a standard Kawi drain. So far I am pretty happy with the Versiplug-R and have no plans of changing it anytime soon.
I have a Versiplug-R plumbed thru the hull and into the engine bay and a Kawi drain plug in the hull should water ever get in there.
