I found a killer pheno of Ice in a 10 pack from nirvana seeds back in 2008, I ran the cut till end of 2009 and my buddy until like 2012 or so. Huge yield, super strong mixed high little head and body, a unique flavor and that bitch would flower in 90 degree heat and still have dense resinous buds when other plants would come out bunk. It was truly a nice cut. I have ran either of your other choices.
