Same here. I like having multiple projects active at the same time, mostly because of the 'switch when stuck' possibility, but also just to give my brain some time _not_ to think about the project. I think I'll go crazy if I had just a single top idea.

On the other hand, when inspired, working for a longer stretch (couple of weeks) on one single thing also works really well for me.

Ah, well, I guess it is a matter of balance (like most things in live :)
