dry lofts race better then damp lofts.
i do think if you can control the pigeon's environment you can keep them winning week in week out most lofts are controlled by the weather.
use what you can to win it is easy just to keep pigeons but to race them to win most weeks is some thing else.
you can have the best birds but if the loft is not right it will be very hard to be consistent racer.
if the loft is poor then the flyer has to use more products to help there birds.
