many roads to Rome as they say, first you must have the right birds then you must put the proper fuel into the bird IMO they both go hand in hand the lofts that are winning at the distance have everything down to a fine art ? what do I know as I have never flown the distance as I said those who are winning at the distance are doing it right and not all doing the same thing or feeding the same the one thing they have in common is there birds are up for the job and they know how to condition them for the task ahead
