Re: Ale yeast?
As Fuzzy said, it depends on what you want. Ale yeasts have the lowest alcohol tolerance so definitely take that into consideration. If you use ale yeast in a must that had enough sugar for wine yeast to ferment, you'll have a treacle-sweet mead with low alcohol. If you adjust your starting gravity, you can have a delightful, fruity/estery table mead anywhere from sweet to dry. See the Recipe Formulation section of the Intro to Meadmaking for more information.
Ale yeasts are great and they'll make a fine mead, as long as you know what their limits are. You wouldn't use a circular saw to cut cheese, and you wouldn't use a scalpel to rip lumber.
