I used Elstree for a number of years flying a slippery aeroplane. The tricks as I remember on 26, or 27 as it may have been then, are to anticipate a downdraught into the pan, having stayed high enough for comfort over the turbulance over the trees, then while anticipating the downdraught, head for a roundout in the pan and a touch down on the line, hopefully being able to turn off at the intersection, but more often than not having to backtrack.
Coming in from the west using the rough bit to flare, again getting the aircraft ready to touch down shortly after the runway proper starts.
