I don't think I will ever follow or sign on to a vote trail. I have seen to many of those that vote on plagiarized and extremely low value content, (one blurry picture and no words).
Manual voting for curation rewards can return a lot especially if it is on content that catches on fire, (kind of goes hive viral).
Comment voting is something I also try to do on occasion, but I need my vote to be close to $0.020 at 25% vote power to do it. I do make exceptions sometimes because I have signed on with dustsweeper to pick up my slightly short votes, but I don't like doing it to often.
