Coincidently I'm thinking of side screens as I nearly always drive 'Al Fresco' -I had the side screens only on once last year when I went up to a FellMog meet and the weather forecast was poor
Still deliberating
As to steering wheels - when I bought my Mog it came with a 14 inch leather covered offset Moto Lita which had a nice thick grip
It was the offset one as the chap I bought it from was on the large side
I liked the thick grip but didn't like the look of the wheel - too small and a bit 70's race car looking for my liking
I changed it for a 15 inch Moto Lita wood rimmed Classic Four Spoke which I thought really looked good but realised that I could have gone even larger as I'm quite slim
So I sold the wheel on eBay (Moto Lita had put their prices up so only lost £30 for about 6 months use) and got another 16 inch Classic Four Spoke but paid the extra to have their thick dark stained wooden grip so it matches my walnut dash and I love it
Big classic looking wheel, thick wooden grip, plenty of leverage
