Firm, fast and furious is fine by me, however, I wouldn't go along with it always being suitable - variable climates, seasons, locations and all that. Sometimes appropriate, sometimes not.
Plus the occasional dose of soft and lush and slow makes you realise where your personal preference lies.
I must say what I reckon to be really horrid circumstances to play in - soft, lush fairways, rough and fringes but with rock hard greens. Now that is truly a vile combination.
