The 21 is my ride since it came out in 2014 so I am confident when I say that I never experience bounces, I always tend to make smooth landings around 270/280 to 310 (when in overweight and using 2. stage flaps) and keeping the nose up in the air and then gently drop it down (since I have the opportunity to watch such landing IRL). Lets say that 7 out of 10 landings are smooth (some wind and turbulence always activated).
It is very much possible and I have been doing it with every FM/Ground physics change to date (guess I can adapt easily). It takes long practice and I even use a 25cm extension since the beginning and fly 99% of the time on the Caucasus map. Sometimes it's really hard to explain to someone exactly what technique to use or how much to move the stick etc. because it's a case of, as we would say here, getting a feeling for the AC and also personal preference on the controls setup (curves, deadzones,...). I very rarely and if ever watch the gauges except the speedometer on landing because of muscle memory and it rarely fails..ILS is another matter ofc. I talked to RL Fishbed CroAF drivers who tried the DCS module and all of them agreed that if it were so easy to fly it in RL, everyone would fly them
