Here you can see a very stable and fast AOKP ROM running on the Samsung Galaxy Note N7000. This ROM is safe from the brick bug, because it is not based on Samsung's official ICS ROM or kernel. AOKP is based on CM9 and it uses the CyanogenMod 9 kernel.
Using it or using the CWM while on it is safe, but you have to take care when flashing it. Make sure to flash it from a safe kernel.
