I have the vaporflys which have been great for road races, but debating if it's worth buying a pair of dragonflys to race indoor/outdoor track. On the one hand, I assume the dragonfly is better on the track because it's lighter, has spikes and is designed for the track. But on the other hand, world athletics banned the vaporfly on the track for pros, so was it actually faster?
Which do you prefer on the track?
