"I have one strain that will give me lots of tops, but I sacrifice big colas. I have another strain that will give me lots of tops AND big colas. Other strains will just divide once and call it a day."

Good to know that Mrs GreenJeans. I have just had pretty good success with FIM on my skunk clones. Ended up with 20 main branch cola's from four plants, but they weren't as dense or fat as the cola's from my first grow. Overall the dried weight was much the same per plant. Actually the best plant from the first time had more weight from a single cola than the largest of the FIM'd ones. I would say other things may have a factor such as light spread over the canopy.

Next time I'm thinking of trying the pinching where you don't actually top the main cola just stun it to allow the branches to catch up as an experiment on one.
