A very high percentage of top sprint fanciers would win out of turn with most of the strains mentioned on this thread, I’m convinced some fanciers would win even if they raced sparrows ;D.
Pigeons for some is a business, the difference between winning with newer strains over the older ones is simple, its more profitable!
So going back to the question re the best sprint pigeons, take a look at the older strains that represent more value for your money. If I had to choose one strain that’s stood the test of time (sprinting) and at the same time offered value for money it would have to be the Wildys.
