Flaps
No flaps maybe in heavy cross wind and without getting too technical...
Flaps can increase lift and or drag, they can slow you down at same attitude or keep same speed with a nose down attitude to help in landing phase with visibility (generally).
Practice of a different configuration can be good but why would you risk your undercarriage more than you need to?
Think aboout why exactly you require a particular flap setting - i.e. what is the optimum for the conditions and aircraft loading etc and with regard to weather and landing distance etc
When you know why you are using a certain setting and understand how to choose you will become a safer pilot - Good luck experimenting
