good pigeons will won on any system providing they are looked after properley by that i mean all the year round not just when the racing season comes around get a good feeding routine there is plenty of info out there on how to feed pigeons at certain times of the year breeding .racing and moulting time .observation is your biggest key as if you whatch the pigeons they will tell you when there right or not imo youve got to be prepared to put the extra effort in if you want to be in the winners list and always remember the races are won in the loft .i fly round about and get my wee turn but still learning cheers
