At the moment, i suggest you not to touch your steem power, you'll be stuck with the running out of bandwidth issue. Wait until you'll have 20 more of steem power.

By that time, who to lend? Go to https://steembottracker.com again, type my name prch as delegator there, and you'll see who's the biggest delegatee of mine. Do the same and Lend your extra 20 to that account.
