I enjoy circuit bashing, as landings are the fun part. Nothing wrong with practicing touch and go's, engine out and other emergency procedures, short approaches, soft field. short field etc.
If all is working smoothly, howsabout the following;
Tailwheel
Aerobatics
Seaplane
Multi Engine
Night Cross Country
Complex / High Performance
Instrument training
Cross Country
If you have an interest/chance to do the above stuff, you will quickly have a lot of different experience and knowledge.
