Thanks for your input, both of you.
I'd probably been better off buying a 3/4 with shield like that Scorpion or a fullface right off the bat, so I wouldn't have a helmet sitting around that I don't like and won't use.
Anyway I decided to snatch up one of those sale fullfaces - it's only twice as much as the snap-on shields I was looking at, probably much more reliable too.
I guess I'll try to sell off that Shoei then...nice helmet but the 3/4 style just seemed to catch too much wind and whip my head around.
