I agree it would be a great idea to allow a winner to choose which prize would fit them most.
If you just start out, the SP could be of great help, because I read a lot of stories about bandwidth issues, and two weeks might not seem much, but a whole lot happens in 2 weeks, and it could just make the difference for a lot of people.
Others, who have been around longer, or have invested some money in their account, are probably more interested in @steembasicincome shares, because the 50SP would make little or no difference for them...
