Some say slick helps more in veggie, sliding over logs, and launching off your trailer be careful on that one or your boat will end up on the ramp! In the mud not so much, but I do know you will end up doing splits getting boat from shore if you ain't careful-damn thing will slide out from under you(yeah it happened,busted my azz and got wet, spilled a beer too).
