Congrats on a good flight, and don't worry about little mistakes. Like you say, they all add to the experience! (as long as you learn from then

)
I know what you mean about the tommy climbing like a rocket. With my instructor in I'm lucky if I get to circuit height by the end of the crosswind leg, solo I'm at it by the end of the climbout
I occasionally forget to turn off the carb heat, since I sometimes forget the CRAP checks, usually when the approach has been alittle more complex then usual (one of the runways that I use has a valley just before the threshold, which means that you've gotta have a curved final leg, but also it can kick up some nasty eddies/sink.
Glad you had a good flight, hopefully I'll get up tomorrow! supposed to be my first navex
