If you want to stay reasonably dry it's no contest

easy up it is
So many different experiences.....With former P4SS I had the old style hood. I stayed dry even during torrential rain. Now I enjoy the comfort of the easy up on my 4/4. Anyway I had no choice because she was ex demo.
If there would be a "next one" whenever, I would go for the 9 stud old style, just because she looks so good. Beauty knows no pain.
One additional experience I made, despite more "work", everytime when I fitted the 9 stud hood, it was a much nicer sensual touch and feel than handling the easy up.
