If Clare liked you that much when you first applied, they'd have accepted you. I know you got really great feedback, and you did get pooled, but nothing came of it, so I wouldn't base all your hopes on any assumptions you might make about Clare. While of course I love the place, if Cambridge is as important to you as it seems, I think you should apply somewhere a little less popular - not the least subscribed college where it's "easiest" to get in, just somewhere that isn't the most popular one!
