I'd advise against SOG with seeds just because:
1) I'm cheap
2) variability from seed to seed
That said strain is hard to choose.
Could go old school indicas that are tried tested and loved like White widow, or Northern Lights
Could go newer school, I've seen Gelato, or strawberry diesel put out some decent colas.
Could run a sativa something like green crack, or super silver haze.
Long story short, try to find the plant characteristics you are looking for like terpene profile, thc/cbd ratio and levels then choose a high yielder from there.
