This is an awkward one because there's no 'catch all' filter. If you want that misty effect on cascading water then 1½ - 2 seconds is ample. If you want that effect on the sea, you'll probably want something in the region of 10 seconds. Clouds are a different story altogether because it depends how fast they're moving and in what direction. You need to be cautious with clouds as well, because they can just go streaky if you're not careful.
10 stop filters are expensive and hard to come by. Someone on eBay has been selling new HiTech 10-stop filters. He's been selling them one at a time and they've been going for about the GBP40 mark, which is not a bad price. I have no idea how many he has and how long he'll be doing this.
