I understand what you are asking, just in order to have F1 or F2 fish, someone in the club would have to have wild caught yellow labs - which I am saying are pretty rare in the hobby (more rare than say, peacocks or an uncommon hap).
Marc said he had some nice yellow labs for sale and you just glossed right over his post. That would imply that simple "high quality" yellow labs were not an option.
There are bags of yellow labs at nearly every meeting in the mini-auction. Over the last 3 years, I've personally sold maybe half of them out there and though not traceable back to the lake, are of good quality.
Good luck.
