Setting the rig like this means the bait sits up off the lake bed by about 10mm if using a pop up hookbait. It allows the hook to lay flat on the lake bed alway from the bait, making it less obvious to wary carp. This alternate Shot On The Hair Rig  provides good bait separation and ensures the rig is hook heavy, making it more likely to catch in the carps mouth.  Though more effective with pop up hookbaits, a bottom bait can be used and the rig will still be very effective as it is still hook heavy.
