Sorry to go OT but amongst the rockets excluding the flare tips which is the most aggressive?
In my experience it's the UK made Red Tip Superspeed. The Reds Tip Rocket
is the same but I haven't used it. They're not built as substantially as the UK Aristocrat
series (15, 16, 21), but they're the super smooth assassins in their category.
I'd like to think that the high end razors these days would be better, but not by very much.
I used my UK RT last night and it usually means I dont need to shave the next day.
