I should have added that, in that configuration, on the back seats I take the sidescreens in their bag - or I use a cockpit cover - for overnight parking.
Also be aware that with hood up and sidescreens off the hood acts as an air scoop and may put strain on the fixing "lobes" at the rear quarters. After a continental trip of some 1200 miles running like this (admittedly c.80mph on autobahnen where it is impossible to stop to erect the hood if it rains) a bit of re-stapling was necessary.
To combat this on p.42 of the December 2014 issue of Miscellany there was an article describing a through-flow ventilation modification (acknowledgement to Rod Bentley) which looks a good alternative to a zip-out back window.
