The nature of the fibers is determined almost entirely by a very small handful of genes and there is no reason whatsoever why KBLB should have any problem in making the fiber completely consistent exactly as has been done already with a wide range of agricultural products.

As long as the genes coding for the proteins (only 3 involved), the spinning and the metabolism of the two amino acids that make up most of those proteins are consistent, a reasonable degree of variation will not only not affect the quality of the silk in any way, but is actually desirable as it will make the worms more robust and resistant to environmental stress. (Which is why the large commercial worm had variability (in the sequence not important to silk production) in the first place.
