best classic Scalextric f1 car

With the next round of classic f1looming I thought I would do some fishing about what is the most ideal car to race . The Williams fw07 and brabham bt 46 seem the car to have but I find these dull and ordinary. Some run shadows and brabham bt44s the Renault rs01 good but to heavy to push the pace . I have converted some wolf wl5s to except Johnson motors and now trying to get them on the pace .so my question is what possibly could be a different front runner that hasn't been mentioned? 🏁
