DS Racing or Max Concept tires for MRC?

MAXPOWER RACING CIRCUIT (MRC)redo is almost finish. Apart from the hardwork & testing done, I need to recommend to the BOSS to close the tires to only 1 brand DS Racing F1 or open the tires to Max Concept Ultra Hard as well... We have great support from Mr. Suah & Rudy of RC Planet SS19 for the DS Racing. As I got free T-shirt recently, wont let them down! hehehe :)

Which tires is more consistent? Which tires is more balance in term of tractions? What about the cost? Let me update you soon!
