OK after seing all the responses here and talking to a few friends, I've decided to give those KW a second chance. I'm going to put them back in the car, in the softest mode.
It's easy enough to remove them that if I change my mind (again) after driving the car a few months, I'll post again
Thanks to all who commented and showed interest and sorry for being undecided and hesitant!
Now I need to find how to close/modify this thread so that people don't get false hopes by reading the title...
