Picture the scene, your fishing a mixed lake of silvers & carp (inc doubles) but you don't don't much about how the lakes been fishing.
Who'd start off with a light rig for silvers & who'd go for a heavy rig hoping for an early lump or two ?
Also, if you were bagging on silvers after trying for carp & failing & then got snapped by a lump would you instantly change tactics & upgrade to a heavy rig or stick with the silvers ?
How many times do you think you're well behind the top places & try for carp later in the match thinking you need something big to catch up only to find out at the weigh-in you've missed out by a few pounds, which you would probably have caught if you stuck to silvers
