hi yellow
all i race is janssens and yes i like these birds very very much it would take a lot for me to change this family of birds they win from 80-450 miles no problem and that is at fed level all the way up to national level, my uncles have clocked them out of dax international and been in the top 15 of the open national result with a janssen, i like day birds in any race and i must say these r the birds for it but that is my personel opinion.
now the van loons dont no much about them but i no they cross well with janssens, i have just got my self a really nice van loon cock which i have crossed with my janssens and took a few late breds of it just to try out and see what happens and see if will beat my own pigeons.
try doing a google search under the names im sure u will get a good history.
