Use the Pro Street Drag ones, they are the most comfortable and yet lightest seats out there....
I used to have a set of Racetrim seats.... they was very comfortable as well, but the foam in the seat will suck up mud and water and it will never get dry, these Kirkey seats also has a variety of different color seat covers and it does not come with the seat, you will have to buy them separate. You can take the cover off in a breeze and wash your buggy and put the cover back on when finished then it is ready for the next ride!!
