all things will work , some pigeons are better with diffrent methods or systems than others ,i think ive tried them all over the years .at the end of the day personally i found whats my system and happy with which individual birds perform under it .have even flown them for a year and found only 1 pigeon that done well,moved the others on ,bred more like him and performances were so much better.i am sure they werent all bad birds , but this suited me. hope above helps,and good luck.
