If a person has a "Silver" Lab that gets some top notch titles and when bred to another "Silver", those pups are also capable of top notch performance, then ya might have something -- but for me, I wouldn't touch one with a 10' pole without top notch titles and pups (with repeat breedings) that are proven to be equally as good.
Good point Doc. Back in the 70's when I was a wantabe field trialer the talk was that yellows were awful ... but not quite as awful as chocolates. I think that's all been disproved by good breeding and really good training ... ask Mike Lardy who I think won the Nationals with a chocolate.
Even though the talk on this forum is "does it hunt", I see a ton of compliments bestowed on how good a person's dog looks, etc. The show people say form follows function (or something like that), the argument being that if they don't have the right conformation they can't run right, etc.
I'm thinking we really want it all.
Crafty, you got a picture of a "silver" lab?
