Skinlink >>>>>>>>>>>>>Baby Monitor. Overwatch Score never matters, it's very easy to manage, especially for a Techno. Grab Cleaner as a CF if you're worried about your Overwatch Score and just keep it at 0. Most of what a Technomancer does, doesn't generate an Overwatch Score anyway.
See Sig for recommended TM builds. I do like the Cheerleader Technomancer Concept. It's just that your Machine Sprites can buff so much more than you can, and squeezing in the Leadership and Charisma gives up a lot. IMO. I've tried building the Cheerleader TM, but was never really happy with it. You're giving up on hacking stuff to get more buffing things when you're already the king of buffing things. Just never seemed like a good trade off to me, but YMMV.
