Very very big well done for deciding to hang up the leather. It is very wise and smart to be able to take such unpopular decision. I think you should sell the creatures (my heart aches thinking we are going to loose two more lovely K75s) BUT if you have very deep sentiments to one, just stop its insurance, hang its number plate as souvenir on the wall, and call the beauty a lawnmower. Nobody insures their lawnmower just because it can catch fire in the garage and burn the house... Wishing you quick and full recovery to enjoy life!!!
