To upgrade or not to upgrade? - PE to UC

Hello all!
Yet another load query question: My husband and I are traveling on VS 20 on 21/2/07, from SFO to LHR in PE. This is going to be our first PE flight, and now I'm worried about not getting any rest on the flight to LHR. Our last 3 trips have been in UC, and of course we love it! I booked PE to save a bit of money this time around, and now I'm regretting it. [:I]
Now I am considering upgrading us to UC on the flight to LHR as we would like to actually be able to get some sleep. I checked the Seat Counter website and Z is showing 7 (most fare codes are showing as 7?), so I guess we would be able to upgrade. I don't have access to Expert Flyer so I don't know what the actual load looks like.
So should we give up our PE seats and upgrade or should we stick with the PE seats? I'm thinking it's worth it... unless they want to charge me an arm and a leg, willing to pay the arm or leg but not both... If not I guess it's lesson learned, book UC & PE flight in advance to secure a better price...
Thank you for any help/suggestions!
