Help sexing RCS?

[textpad]

Hi, I'm new here, so I wasn't sure whether to post this under breeding or invertebrates, but I recently got 5 RCS and would like to start breeding them. They've pretty much all molted at least once since I got them and I think they're almost full grown, but I'm not sure whether I have any males or if they're all females. Can anyone help from the 4 pictures below? I haven't seen any saddles yet.

Thanks,

Don't know if this helps but on this pic, if you enlarge it, you can easily see the saddles on the females. The male is less brightly coloured, more dappled, and obviously doesn't have a saddle.
