::whips out the guide book:: I was weak, and besides, it makes things so much easier...
Try to have CON at 14, it offers the best range of mid-level implants...
Physical Boost Package CON +1, DEX +2, STR +2
Mental Boost Package CHA +2, INT +1, WIS +2
Insight Implant WIS +2, Will Save +1
Biotech Implant Regen 1
CON 16 opens up even better ones...
CON 18 opens up even more, although those are the most rare implants out there - and unfortunately you can't build them - that would have been amazing. Hey, listening Devs? Let me build Implants next game! Please?
