The best way to help hone stick and rudder skills is to get an instructor who can actually fly and handle a tail wheel aircraft. I.E., conventional U/G. Very rare today I am aware.
I would suggest a Piper Cub or better still a Cessna 180/185. When you are competent in such a machine, those skills will benefit you in the future. Even up to and including heavy aircraft, "near the ground". I can still be sure, after a flight with a pilot, if they have operated a conventional U/G aircraft in the past. These skills are sadly lacking today.
A few hours in a glider wont go amiss either as that will assist in the illustration of adverse yaw and the above..
