Just a caution with regard to slipping, it stresses the vertical stabilizer and in particular the fixings that hold it in place
Are you saying it stresses them beyond the designers planned normal use stresses? Turning increases stresses on the wings. Landing and taxiing cause much greater undercarriage forces than flying. Running the engine stresses the propellor and engine mounts.
I sideslip because you can add/take off sideslip without taking a hand off the controlls - and it is used in crosswind landings.
