Just a point on roll-hoops & storage.
Not sure if you have, or are considering roll-hoops - as fitted to the Speedster. They take up a proportion of the storage space behind the seats, so you need to think about where you would store the trad hood when its off. I my case, Williams made a hood bag, which is strapped to the rear rack. Also, I'm not sure if or how roll-hoops may work with an easy-up hood given the clearance tolerances when opening and closing hood. In my case, with the traditional hood, its worked out well.
