Jaco's are the best foams out there. Speedminds are ok but you'll have to adjust your car setup alot and they'll be harder to drive consistantly with. Trc's are ok but imo don't give as much traction as jaco's. In the end jaco's are awsome, keep the car planted and alot of steering on tap. Jaco orange/dbl. pink - dbl. pink works great.
