I find fishing with a partner you cover more water and sometimes find out what the hot bait of the day is. Crappie fishing with Tbayboy this spring the fish seemed to like his white / pink jig head this one particular day, as soon as I put one on I started catching fish also.
Flipping in tight spaces I prefer to do myself, as you don't have to worry about boat control as much.
Carp fishing I go with Photoz , he has enough ground bait to feed a few hundred carp(thanks Photoz)
