Hi Oscar,
I do not have anything against people wearing a Yellow Jersey during a ride, but I would not wear one myself. Why? Because the Yellow Jersey does not just represent a team, it represents an achievement. It's sort of like buying yourself an Olympic Gold medal and wearing it for all to see. As for me, I'll stick to my $6 Philippine made team jerseys. Don't get me wrong though, I do not think that cyclists in Yellow, Green, Pink, Gold, Polkadot, etc. jerseys are posers. Whatever your choice, I'm sure you'll enjoy your new jerseys!
Cheers!
