I have been doing exactly that. Everything straight to Steem Power. My long term faith and support is with Steem. I'm also very new to the Steemit platform still and I need to power everything up so I can get to a point where a vote from me reflects how I feel about a post. At this point a vote from me is like dust in the wind. I don't know how much longer the trend of SBD being higher than Steem will continue but I will be taking advantage of that disparity as much as I can.
