Those are the ones. They make a "huge" difference on a stock length V.I've got some 24in paddles for sale in the classifieds, you should check em out.
I ride with guys that run both. The extremes will give you a little better launch and the edges will be better for turning under throttle. Both great tires. You need that flotation on a stock length V.^^ x2.
I've never run the extremes so I cannot compare them to the edges but I know the edges worked really well for me.
