The strop is much softer than the hone. Feel free to strop at blazing fast speed if you like, no harm will be done.
The red powder is supposed to be on the strop. It's the Rolls Strop Dressing, and it has mild abrasive properties, meaning that it provides a small amount of sharpening to the blade.
The biggest issue you will face with the Rolls, is achieving true shave ready status for the blade. Most of these blades are no where near being sharp enough to shave with, and I am not convinced that the included strop, and hone are sufficient enough to return a dull blade to a shave ready state. If you truly wish to use the Rolls Razor you will likely need to send the blade out to be honed (user Ambrose has the most experience with this).
It's basically a straight razor, and hence straight razor shaving technique is used with it (shave with the blade nearly flat against the face, and stretch the skin to create flat planes to shave).
