Yes WSE's GDP does look good and going by the encouraging feedback/reviews of GSC that also looks pretty good, some GSC can get up into the high 20's too. I like how GSC and GDP are involved in the genetics of a lot top strains. If all 3 were at the same strength I'd probably go for GSC first and GDP second, but if Godfather OG's potency is suggested to be several points above those two, which if that's so it would be hard to go past and probably be my first choice! That's the trouble with growing outdoors, you only get one punt at it and then have to wait another year to do it again.
