1st grow almost done, need advice on 2nd!!

I have atleast 2 options for my second grow... i need to know which to do!

1. Reveg my plant and take clones for a SOG?(for those who havent seen it check out my signature, it links to my journal)
i measured a container i have and the inside dimensions are 20" long x 15" wide x 14" tall... which comes out to about 15.6 gallons of soil. Would it even be worth it to do a SOG in this space? If so, then how many clones in this area under a 250w hps? What would be a likely yield, assuming i have no problems? This strain was very hard for a beginner, with it being very sensitive to nutes and water.

2. Just do the Northern Lights from seed? (not feminised, i plan on making seeds when the time comes) I plan to only have 2 NL females in flower (LST'ed, but not as heavily as my current plant)

I plan on using about 59% foxfarm ocean forest, 20% foxfarm lightwarrior, and about 29% perlite with either option i chose, but starting the seeds off in just lightwarrior.

What do u guys think i should do? I am not growing for profit, only for personal/friend use.

Revegging and taking clones will take 6-8 weeks, then 8-10 more weeks to flower.

Growing NL from seed will take about the same amount of time, asumming i veg for about 6-8 weeks.

Basically im asking this: Which will yield more, assuming i have no problems with either grow. 2 LST'ed plants or X plants in a SOG?
