Interesting take.
As always, history in this field is clouded.
But the way I remember it was Breeder Steve getting a breakthrough when DJ Short wanted to collaborate with him and shared his Blueberry seeds (back then still fresh out the oven so to speak).
Now Steve didn't rip him off like DP and Sagarmatha but he also didn't collaborate with DJ the way he expected. If memory serves, basically DJ wanted to be involved and Steve just took his Blueberry and did his thing with it and was very successful, creating stuff like Blockhead and SweetTooth from it, strains that are still found in hella crosses to this day.
Anyway, as far as I know, Chimera came way later, when Steve was already looking towards growing wine and stuff and SOL was towards the end of its existence.
When I did research on strains, I did see that Chimera's work incorporated a lot of Spice of Life stuff and just assumed that it was based on it, meaning that Chimera crossed some SOL strains to his own stuff.
This is the first time I hear that Chimera was in any way or at all involved in SOL breeding work or ever worked with Steve.
The way I researched and remember it, Steve's big "colab" was with DJ Short and that's where all his breeding success came from. Afaik, SOL just went down hill after, not due to lack of interest or strain conservation or anything like that but just because Steve got disillusioned with "the game" and switched over to growing wine grapes and wine making.
And I always assumed Chimera just got his hands on big piles of leftover SOL seedstock and did his thing with it under his own label.
Anyway, regarding SOL seeds:
I decided against buying them 2 or 3 years ago when they were already at least 7 years old (likely older). While I do regret that decision a little at this point (particularly because they were Blue Satellite 2.0 seeds and that is the most interesting SOL strain to me, aside from Sweet Tooth), I don't know if I would buy such seeds, even if I found them, now, several years later, when they would be AT LEAST 10 years old...
The only way I see myself getting any SOL seedstock or genetics in my hands is through somebody who grew the strains themselves and F2ed them. Or kept a clone alive all this time.
Or if I get 10 year old original SOL seeds at a price below 2 or 3 bucks a seed. I might still do it then. But not for 5 bucks or higher, no way.
Kinda similar situation for me as AK47, Bubblegum and Blueberry. All strains I desperately want but no seed source that makes me confident to pay more than 2 or 3 bucks a seed for it. With those strains as well, I would only feel confident in getting seeds off market from someone who grew and preserved it or kept a clone.
