I'm looking for a new Kooba, and debating the Paige and Seinna. Any thought on size and how comfortable they are wearing and using? I have a couple, the Marcelle and Lucy. I'm wishing for something that I can wear over my shoulder easier, as I have small children and usually need my hands free. I'm 5'10" and do not like small bags but really don't one the size of luggage either. Feel free to put your two cents in, I'd LOVE to hear what you have to say if you already own either of these styles. TIA!
