What are the shortcomings of Jason Max playing Van Loon?

The shortcomings of Jason Max and Fan Long include being intolerant of long-distance flying, not good at flying in one-day races, bad weather, and difficult to train with little training. For the pairing, the matching method of pedigree matching and eye sand matching is to pair the peach blossom eye male pigeon with all the Van Loon female pigeons (chicken yellow eyes). The offspring they breed (including the young pigeons of the year) have won many high positions. Award, Van Loon pigeons are matched with Janssen pigeons, and it is easier to succeed if the eye sand is matched differently (peach blossom eyes with chicken yellow eyes). In terms of pure pedigree, it is better to pair up with Janssen and Mourimen. They have the same roots and ancestors, and they are also suitable for breeding after pairing. The disadvantage of this pairing is that the pigeons are fast in sunny weather and are not good at flying in bad weather.
