One suggestion from an experienced Steemit person,

For the time being DON'T select the payout in 100% Steempower. Under current market conditions do the 50/50 split. Then we you get paid, you take your SBD and sell it on the internal market for Steem.

You will get more Steem that way. THEN with the Steem you bought on the internal market you Power Up those Steem.
