I think jsec is on the right track. My motto is when the fish truck is here, the fish truck is here. Accordingly, I would probably put more than just 2 lbs. of GSH in just because Rex will have them, and at $9 bucks a pound or so, why not. I'd put in at least 10 lbs. And I do believe that jsec's pond is currently loaded with bait fish after his April stocking.

Regarding the YP and SMB, jsec's goals need to be stated, and then considerations for the size of each the YP and SMB stockers, to then determine optimal quantities of each.
