That'd be a good call - I like the aeroscreen a lot, but am planning a trip to the Alps next year - so a screen and half hood is hovering in the back of my mind.
The westy for me has achieved something I thought impossible - it has satisfactorily replaced my long time addiction to motorbikes - and that is a statement I honestly thought I'd never say!
It is a hoot on the country twisties - and requires a similar level of concentration as a bike (being all small and vulnerable). This is something in particular that I like, as it means my head can only work on driving and staying alive which in turn means all of the day's problems that filled my head get neatly put away and this (for me) magically helps solve subconscious issues, whilst at the same time providing a nice shot of adrenaline!
Now, if only I didn't have 300 hrs of work to do this month! (right, back to it)
