I wish I did the same.... I had 2 chernobyls at the beginning of this grow, one just grew to good to be true, but it was and ended up being a very sativa looking male and I chopped it down not wanting to chance an accidental burst in my tent, however 2-3 weeks later I'm wishing I saved a few cuts of that male to do the same thing. I still have 6 left out of a 10pk of chernobyl left so I'm sure theres gotta be at least one in there, however I'm more inclined to grow out those looking for that lime pheno you have, not exactly sure what the one I have is yet but the leaves on my cut look a bit thicker/more indica-ish than yours, but so far she's the farthest along in my group of 10-11 plants in bloom (way to many, 4 per light max for me next time).
Good luck, I'll definitely be hanging around to see how yours turn out.
