"big buds" are just larger collections of smaller buds. I don't see the fascination with huge colas. If posing with a soda bottle and a "thumbs up" for a totally awesome pic, whats the point? Youre going to break them into smaller buds to store and even smaller pieces to smoke.
I would rather have a plant full of dense golf ball buds than a towering cola that develops bud rot anyway.
Anyway, the main shoots or the ones that are closest to the light will develop the largest clusters. Training so that many bud sites are exposed to equal light intensity and removing shading fan leaves will give you dense buds all over the plant. You wont get those long "donkey dick" things but you will get a plant full of premium bud.
