Yes you could choose a chart in AA50 and G40, but it was one of 6. I like the idea of groups of 3. I agree with you guys that 6 is too broad, but I also think picking the tech you’re going for (group of 1) is too narrow. I just really like that group of related 3 idea.
I apologize I haven’t even tried to read every post that’s here about tech, but just wanted to suggest the tech token idea from AA50. Nobody played with tech in G40 for good reasons, I think. First of all, they were kind of lazy in just keeping it with 2 charts of 6, and getting rid of the tech tokens made it too risky at 5 IPC’s anyway, but I think the biggest reason is because with so many more options in G40 than AA50, it was too much (for serious players anyway) to be worried about whether your opponent would suddenly get paratroopers or long range aircraft or something. I’ll just stop here, just wanted to toss those ideas in the soup.
