Are both cars in ST, or what class are you in?
If you have a lot of elements, is it a lot of slalom type stuff, or 90 degree and greater turnarounds.
If there is slalom stuff and places where you can keep it in the SVT's power band go with that.
If you're slowing down quite a bit, go with the ZX3 torque and gearing to get you back up to speed quicker.
