I'm A "Trim" Freak, and I need some help!

....I admit it, I don't like diaper butt. My son wears MEOS with no inserts and no cover right now b/c it's so warm. They're so trim and happy on him and he's so comfy in them. He doesn't like the bulkier, full dipes either, and will tug on them and fuss. But w/out the inserts or a doubler they're only good for one big toddler pee. No worries, b/c it's summertime and who cares about frequent changing when he's only wearing the diaper anyway!

But I'm already getting nervous about winter. I cd'd through last winter with prefolds and covers, and don't have the appropriate size anymore. And he's a toddler now, running around and I'm no good with the snappi when he's wiggly. So......I have about 2 dozen ME doublers that I've been laying into a Bummis Original cover 2 at a time, and that works well when I can't leave him coverless and don't have any dipes left. It's fairly trim and easy to change, not to mention how fast they dry on washday! But they're not absorbant enough for longer term use. I'm looking for really absorbant, trim doublers so I can diaper like this when the weather gets cooler and he can't go sans pants. But no fleece toppers, so mf is out, unfortunately.

Suggestions?
