I echo Monocock's sentiments. Get used to a Luscombe and your skills will improve. Sideslipping down from the trees on 03 at Popham is a very useful skill and very good with a crosswind as it straightens everything out for you.
So everything suddenly went quiet and the only tenable field is short and awkward with a crosswind and obstacles on the approach. Being confident with this skill could be a lifesaver.
Apart from helping you with sideslipping the Luscombe will also improve your approaches by making you nail the right speed.
Sideslipped a 172 all the way down to the runway last year on my BFR in the US last year after the instructor gave me a PFL with flap failure. It was very well behaved but my right leg muscles were getting tired. I imagine the prohibition in slipping them with full flap is because the turbulent airflow off the trailing barn door is running spanwise and screwing up the effectiveness of that aileron.
