I didn't like the flat board base shaper in my Speedy 30. It was too stiff. I do like to use my extra sturdy Chameleon insert in my Speedy 30. In my Galliera PM, I like the Purse To Go insert.
Base shaper for sure...an extreme slouch just doesn't appeal to me. i use one in my speedy 30 and in my trevi pm...love them!
