Welcome to Flyertalk and here at the BA board mattcasey94

Sounds like a 77L? See the Wiki in the linked thread below.

You can have a look at the thread below which gives some advice/views too. If its a 1-2-1 layout then that's definitely club suites. Worth keeping an eye on though as sometimes, not that often, but aircraft types/swaps can happen so something to bear in mind.

Personally I'd pick the front cabin. 3K/4K if you want a window.
