I personally invest rarely. If I syndicate, it's because there's something I love about the company that I think others will too. Many do - of the few I've done, there are a few acquisitions, and a few follow-ons from the likes of YC (FlightFox) or A16Z/Founder's Fund (AltSchool).
Where I lead into a primary investment with my own money and have over a $100K allocation, I will put on AngelList. Distribution is subject to approval of company founder, of course, and it must meet criteria that would make it feasible for funds (no pass-through tax LLCs, etc.).
