For me in sprint racing it's all about systems and position and wind direction on the day. Flying in a Fed like mine where the majority are inland fanciers (to the coast), flying for big money every week the competition is as hot as you'll get anywhere in the country, I've found that some breeds of sprint pigeons can't hack a head wind or a lack of sun, or a bit of rain. However I've tried a lot of them over the years and for me the Van Reets tick all the boxes, weather/wind conditions.
