thing is, my scrog is flat - well dished i guess, but with a 250 and 4 square feet i have 60 odd watts per square foot wich is close to optimum. i dont get bigger buds in the middle so i know my light ditribution is pretty even, and i got well over 1g/watt last run with strains chosen for smoke rather than high yield, so im intrrigued by vertical but wonder if i could do much better than i'm doing already. also im not convinced that aplant can use horizontal light quite as efficiently as vertical light.
great that there are so many methods to choose from though, we should all find one that we believe in and that works for us personally.

Verdant, i've gotten similar results with flat scrogs. I feel that light is light, and vertical or horizontal, it will grow you some nice plants. With vertical, you need to keep your scrog very even to get awesome results, so that nothing is covering any buds.
