In my games, (usually 4-5 player) we always discarded the techs that were 5 or higher. the games never (in our case) lasted that long for every one to get anything great. So we were setting up and everybody said not to bother with tech, despite that it's cool, it's just to hard to get. So i thought during our game (which i lost ) i thought of this variant:
Setting up- this step is the same as usual, nithing new, get 2 techs, keep 1.
Reaserching- this is the new part. Now,what you do is research with up to 3 ships, BUT any techs that can be completed in one turn must wait till their next turn to use it. Otherwise, it is normal.
Results/testing- Iv'e done about 6 games with this, and it was balanced and fun!!! aliens were the same, to keep a constant, they were zombie, shadow, masochist, and mirror. The rule for instant techs was so you can's spam tech cards every turn, i did 2 games with it, and it was surprisingly powereful. getting the prometheus (my personal fav ) is now only 3 turns to get, and it was not overly powerful with any number of players, as i did 3 and 5 player games as well. this makes it easier to get the really good techs, not waiting 9 turns for the coldsleep ship and only waiting 3 turns. This is also risky, and your using up ships MUCH faster than you normally would, which was also surprisingly efficient, as 3 or 6 ships meant victory or defeat. This really makes the tech fun, usuable, and now people actually want to use them! Please reply for your thoughts!
