I like the breakdown you gave, I'm feeling a bit more optimistic now about HF19. I'm usually in the 90-100% range for voting power so it sounds like I'll be in good shape here.
I heard that if I reduce my voting power, I'll be able to reward more content creators every day. Is that a fair statement? Which way is the most rewarding for me?
That's only a concern if you find your voting power going down so much that your vote is no longer very valuable. It you're in the 90-100% range most of the time, then it seems that's not a problem and you can already vote for more people before you're notice a difference.
The more value you distribute, the more curation rewards you get, but it is proportional to the strength of your vote. Best bet may be to experiment a bit and see what works for you.
