Hello fishking,
One reason for an increased catch rate using the worm rig unpegged is that
the slip sinker is free to slide up the line after the hook set and during
the onsuing battle to land the fish thus depriving the fish of the leverage
of the added weight next to the hook. This helps prevent the fish from
throwing the hook.
I seldom use a pegged worm rig, but there has been occassions where the
faster fall rate of the pegged worm was just the ticket to provoking a
strike.
Hope this helps somewhat.

Keep yer line wet and yer fanny dry.

What circumstances do you use pegged V.S un -pegged weights. The majority
of
the time I leave mine un- pegged. I read an article that leaving them
unpegged increases your catch rate over pegged sinkers, forgot what the
reason was but it was in I think it was in last months bass magazine. So
which do you prefer?
