Storm still spits out the Roto's.
My you can see how mine is laid out in my profile. As far as where it'll fit, if you drill it moderately tame, it should fit right where you say it'll go.
If you drill it strong, like mine, you may see some overlap with your SCB. Not a lot, as the SCB is a bit stronger, but the Battle will cover the heavy almost as good.
