Ian, it doesn't seem to matter how dismal the weather might be .. nothing stops you from making beautiful images. Splendid work, AGAIN! Do you find, like I do, that it's the poor weather days that make for fabulous light? Sunny weather with all its harsh shadows is so ...... pedestrian. Keep shooting on the "snotty" days!
You are right, cloudy bright days for me are the best for my style of image as bright sunny days with harsh lighting and heavy shadows have their place and very often produce very dramatic images, but the cloudy is better.
It is all a personal choice and this is my personal opinion on what works best for me.
Like Arie, I also like the challenge of producing usable images on challenging days - it's what makes photography fun.
