Sumo rod racks are the perfect way to carry your rods on your car. You can quickly grab your rod when you see that blitz on the shore... There is no “better” system as both types have advantages and disadvantages. There is however a few factors that are important. You should consider how you are going to use the SUMO to help in making a decision: If you are going to drive above 45 mph then you want the suction mounts. If you are using the SUMO in really rainy conditions a lot and NOT going to drive above 45 mph AND you remove the SUMO from your vehicle when parked while fishing, magnets may be a better choice. SUMO suction and magnet mounts are interchangeable and sold separately so you can use any combination for best results. Magnets Magnets will only adhere to steel surfaces (check your hood and roof with a refrigerator magnet to find out). Magnets are less sensitive to temperature, dust and water on the car’s surface. Magnets will work in extremely cold temperatures. Magnets require flat surfaces for optimum adhesion. Suction Suction mounts can adhere to any smooth and non-porous surface making them more versatile than magnets. Properly used, suction mounts provide vastly superior adhesion and can withstand much higher speeds, crosswinds and really rough “roads”. Suction mounts can adhere to slightly curved surfaces. Suction mounts are more sensitive to cold temperatures and wet and dirty surfaces. Really cold, wet and dirty surfaces can inhibit adhesion
