Ok quick response before I go out on one of my favourite drives up the Yorkshire coast.
The Aeroscreens are laminated glass.
I wouldn't venture out with either screen option on motorways or A roads without my full face helmet:

Howard..the point I was making was that it is not uncommon to see lots of Porsches and even Ferraris and other exotica on the roads but hardly ever a Morgan !!!..we all like individuality as petrolheads I think.
70 mph with aeroscreens or cut sown screen feels like 170 mph and it is the nearest I can get to a motorbike for exhilaration.
No such thing as bad weather...only the wrong clothing .
I have other vehicles for transport but the Morgan is for fun fun fun.
