Back to basics
The idea is to be in full control of the aircraft in all phases of flight.
A flare....a check.... both work.... a slight dip below the glide slope when VFR works.
The important point is SPEED control, and using the available runway length in a professional way.
I also used to love landing the C1 and 2, on the mains and try to turn off the runway just after nose wheel touch down.
In the Hawker 700, full aerodynamic braking and just touch the brakes.
But I was BAD I did use the trim wheel. I was severly chastised by Mr CAA one day, he was correct, what about the Missed Approach trim.
The G450 and G550 Gulfstream are slightly different on flare / check and nose attitude, but still always try to make a gentle touchdown.
My ex Co Captain was fantastic at this, every time was so smooth, but he did use all of the 10,000 ft runway.
