If youre looking for the best options on any s1’s i always recommend CSI if caleb has them available. He has a great reputation that was very well earned.
imo S1 will be better then cross.. after all, S1 will have high chance of being same as original.. in cross you will have GSC with undertones of second strain.. I had GSC S1 x Cocoa Kush and all phenotypes were very kush, there was almost nothing from GSC..
