Big Bud is a strain intended for commercial growing/ $$
but i would go with a Big Bud x White Widow or a Big Bud crossed with something else. as someone said above it is better to get the best genetics possible (quality) and then work on improving yield.
OR I would go with a heavy sativa that is long in flower, grow it 12/12 from the start so you dont lose much time, but the long flower will give you time to adjust to your plants, and figure out what they like. Time = experience dude, and it takes a while to get your method down
