I just finished a run of ice, it's top notch.
I have tried jock horror, aurora indica, chrystal, bublicious, eldorado, and ice all from nirvana and aside from the jock horror and a keeper pheno chrystal I found ice ranks in at the top of the gear that I have grown from them.
I found two distinct phenos with 15 females and both look the same after manicure/dry/cure, however pheno 1 is more dense, finishes much faster but unfortunately does not yield anywhere near as much. The potency/high is the same to me while the 2nd pheno (the slower/higher yielding strain) smells much better after curing then the first.
I have another ice in flower now that was also started from seed and it looks to be different then all the other ice I have grown. It is much more frosty at 5 weeks 12/12 then any of the other ice I have finished, however this plant received a longer veg then normal but I don't see how this would effect resin production.
