I recently played with the F.I.M (Fuck, I missed!) method. Unfortunately, my test subjects were two males and one hermie, but I did infact convince 6 shoots to fight for the top.
I highly recommend this method but only for early-mid veg, and I believe the biggest difference(from topping) may lie in the shape of the cut, ie. the V as opposed to a straight or angled.
Good luck cussin' n' missin'!:thumbsup:
