I called and reserved 8A for both my outbound and inbound and had no problem as *G reserving them. On the outbound, however, I got moved to 14K (completely full C). No problem with the 8A on the return.
In retrospect, I actually liked 14K better. I would choose a K with the table on the aisle side. Protects you from being bumped by traffic. 8A was great while I was awake. However, when sleeping, my feet and legs felt trapped. Having the one side open in the K seat was much more comfortable.
