.....even though you could'nt edit, the question posted.
.....because I am not familiar with the other strain. Several years ago I purchased 40 Dr. A's Northern Lights seeds and got 100% germination rate. Started 10 at a time each time. 38 of 40 were the same phenotype, 1 was extremely tall showing the Thai background. Named her "Amigasa" (Big Friend) and still have her through cloning. Massive yield of top quality flowers outdoors, but she takes a while to finish. Very good yield indoors as well.
The other pheno was an extreme Afghanica type, short and fat, named "Gordita" (Little Fat One). Used her as a mother to create an F1 hybrid with a White Widow male which was tall, branchy and had tight internodal spacing. Have one female daughter from this cross which I have named "Sugar Mountain" for the copius amounts of trichromes inherited from the White Widow. She also clones easily. She is tall, has long branches and close internodes like her father, and huge fat colas like her mother. MASSIVE YIELDS indoor and outdoors.
Created a few hundred F2 seeds from the best male and best female of the "average" 38 remaining specimens. This generation seems to be the same phenotype every time I germinate them. Yield and quality similar to what I've described above. Popped 10 of these a few weeks again looking for a suitable male to pollinate Amigasa and my other 18 females mommas I have from various other strains.
Have tried about 60 various strains from Canadian, Dutch and Spanish Seed Companies in the last 9 years. Dr. Atomic Northern Lights was the best investment I've made buying seeds in this time frame. In my experience, only Neville's Northern Lights #1 and his Northern Lights #5 x Skunk #1 (currently Shiva Skunk from Sensi Seeds) equal Dr. Atomic Northern Lights. Hope this is helpful to you. Keep on rockin' in the free world.
Who's the Blueberry X C99 from......Wally? I hear His Blueberry Jam is good, bit of selection but supposed to be good.
Goodluck with your choice.

I just purchased 10 seeds off of seedbay that are NL x Blueberry from Dr. Atomic. Wish I could give some relevant advice...but I haven't grown any of the strains you mentioned.
ended up going with Blueberry Jam NL x BB
From what I understand Blueberry Jam is the NEW atomic nlxbb
... and from what I read in one thread the original atomic nl x blueberry was better.
But thats not from my personal experience so take it for what its worth.
The post I had read said something like "dr. atomics OLD nl x bb" ... it was still a dr. atomic strain being mentioned ...
blueberry crossed with romulan ??
that sounds killer
