Welcome to Flyertalk and welcome to the BA forum Leanne Clark. These seats are fine from recline and window point of view, the big downside is that they can be noisy, both from the turbines and the amount of traffic to the galley and WCs at the back of the cabin. The other issue to bear in mind is that fleet changes are happening at a huge rate at the moment, so I wouldn't assume that a particular aircraft type is going to be assured.
