Hey Fatima
Just a few bits of information regarding the brands you are looking at.
I have size 13 feet, squeezed into 12 boots like you. I spent a whole day Demoing Stepchild Boards and while I like a few of them a lot. They just don't have a board that will fit your feet man (believe me, I tried everything thing they had lol). The only thing that kinda fits is a big powder board, but thats no fun.
I'm not surprised you're over your Forum, every forum cambered board I've ridden has been stiff as hell! So if your after more flex then just forget about forum unless your going to buy one of their rocker boards. (But keep in mind they haven't been making rockers very long)
Libtech and Gnu are sweet.
And think about some other brands too. Whether people like it or not, Burton is the biggest brand for a reason (not always the best but they have to be pretty damn good)
If you do end up getting a rockered board then I recommend an Arbor. That's what I'm on at the moment and love it. It's really good for guys like us because the board widens around the bolt holes (it's like their version of magnetraction). It works really well for stopping the rocker from being too washy and you can ride them with a size 12 boot but not have a super wide boat of a board.
Hope that helps a bit, looking forward to see what u end up with
