I've got the kr-1 version and highly recommend it. It is extremely comfortable once it warms up from your body heat. Molds to the shape of your back and moves with you, I don't notice it at all. By far the most comfortable back protector I've had from A*, and I've had quite a few of the recent models. Example, the bionic line was a very rigid hard plastic that prohibited movement and seemed to ride up a lot.
The nucleon line breaths really nice as well, and the kr has a wide range of adjustability. Can't go wrong with the level 2 protection.
The only other piece I was considering was the Forcefield Pro Sub 4. From reading reviews, it is apparently really thick. Requires a jump up in suit/jacket size. I didn't want to purchase a new suit just to accommodate a new protector, so I went with the A*.
