Hey essence, they look like they've made quite a bit of progress over the last week. Don't know about anybody else's male/female ratio when they go into flowering but I usually get more females than males, so you may end up with a couple more females than you think. I had the same question scrog v lst and have decided to go with lst. The only reason being you start scrogging before flowering and as I've started from seed (same as you) by the time I find out the sex the males are gonna be hard to remove from the screen and they'll leave a lot of holes that will probably be hard to fill with the remaining females. It'll be a lot less hassle when you get some clones and know the sex and don't have to worry about removing the males.
