I'm always up for a meet if I'm free.
The B3306 as suggested is a great road, in fact there's so many good roads in west Cornwall. Tbh though the b3306 can get busy in the summer and there's not many overtaking opportunities so I would make the most of it before then.
I quite often just go for a Sunday drive on the awesome roads down that way, next time I know that I'm going ill stick up a thread so ppl can join me if they fancy it.
