Same. Paired with a sharp blade they’re awesome shaversFeather.
If you want smoother go Gillette black (India) blade.
I've used an Astra for some time now in my Red Tip. Good choice.Red tips and other Super Speeds work well with most good blades, although I like to use Astras or Polsilvers.
Try what you usually like to use and let us know how it goes for you.
From my experience with my super speed I really like feathers/GSB/or even astra blades might be a good choice. Especially if you want that close shave. Where I have no problem with irritation with those combinations. The blade is personal preference.A very subjective question and I have alot of differant types of blades but what would be the best blade for a heavy growth coarse beard.
Any recommendations
