Cool, I'm not too familiar with Smartsteem except for the fact that I've used them for upvotes in the past. Maybe they payout once a week or something. You can also check out @jerrybanfield who claims to payout 64% per year on your delegation which is one of the highest I've seen. Or yeah, MinnowBooster is solid as well. But you're right.. you just gotta dive into the deepend with Steemit lol.
