New helmet – should it be a folding helmet?

Hello together, I need a new helmet again. Actually, I find a folding helmet quite interesting – but I have always ridden integral helmets so far. Price is first of all incidental – during the rough browsing I came across the usual Schuberth C2 & C3 and the Shoei Multitec. At my present I have mounted a Cardo hands-free set – I think this will not fit with the C3 because of the sun blind operation. Can you tell me anything about the helmets or folding helmets in general? A ch yes – driving profile is rather toury to sporty, but may also go a little fast on the highway… Best regards Stefan
