I can understand why Alex doesn't like the Aquadapter or the Aquatap. At height our A/D does add quite a weight to the end of the pole. So all the work Alex is doing with regard to brush weights is being undone by us adding extra weight with another accessory.
My SIL's SLX22 was so much lighter when he removed his A/D when the lever arm spring broke. But his tap contraption he put together on his base pole was the pits.
I'm looking forward to this new Univalve.
