Yes, stock 3" or > straight CNBG. Reason being that the Hybrids will not breed enough offspring to support the LMB population. The FHM will probably sustain them for most of the first year, but after that the FHM will be too small to sustain the LMB.
Think of it this way. How well would you grow if all you could do is eat 1 tablespoon of food, then had to walk or run around the block. That's equivalent to the 3 year old LMB eating a FHM.
Now what if you could eat a hamburger instead of the tablespoon of food while expending the same amount of energy? You'd put weight on quicker, right?
