If you're happy with your four and aren't going to use the fifth just apply for something weird, apply for the most obscure degree you can find just to see if you can get an offer, might be a funny thing to say to granchildren someday.
Otherwise go mid-table, somewhere between 10th and 20th (in no particular rankings, just in approximate position overall). York, bath, durham, manchester, nottingham, soton, leeds, sheffield, kings college...Bristol if you feel more confident and not sure how you feel about scotland.
