For standard fishing the Drennan range will catch you pretty much anything you want but I like a curved shank for some of my fishing, a long shank for other times and the marvellous QM1's for another. I tend to carry a wide mixture of hooks and although my carp bag has them in their packets, my barbel/other bag has them rattling around in the compartments of a little plastic box. But I always have a sharpening stone and a jewellers eye glass to check and hone the points when necessary.
Of course any hook tied incorrectly will loose fish so knots are another topic that could be discussed till Doomsday
