Hi Ron, You are right, technique needs to vary based on razor aggressiveness. I rotate between two razors, a mild King C. Gillette and moderate Weishi Long Handle. Can get BBS with both but to do so requires changes to my technique. With the milder King C. Gillette an extra pass is required (3+ instead of 2+) with the final "+" touch up pass based on approaches such as "riding the cap" if BBS is desired. Also the King C. Gillette is a heavier razor so there is more pressure on the regular passes versus the Weishi.With a aggressive razor you can regulate it like a adjustable razor but on the fly once you dial it in.
For myself I have some aggressive 3pc razors and the best way to master them is with steep angle (riding the bar) with a short handle give some spectacular shaves irritation free mostly(blemishes can get sliced off easily). It is mostly blade feel on the fly is the best way to describe the shave. The short handle reduces leverage and weight and quicker to respond + good to hold the steep angle at the bottom of the neck area with out scooping out to complete a stroke.
Good luck with your razor hunting!
