BTP & the other grandiose contests

How about making them multi-sponsored contests? A Hypothetical example would be having BTP sponsored by several different books (the more, the better), and give the SBR members the option of choosing any of the participating books (like on the pro application) to have the prize money credited to. How many people did not sign up/deposit for BTP last year because the one sponsored book was not to their liking? Or simply because the inconvenience of signing up/depositing at a book they have no previous experience with? Having a multi-sponsored BTP contest where SBR members have the option of multiple books to choose from will be a huge convenience to the players wanting to participate, likely lead to at least twice as many depositing players for the contest, which will equal more money for SBR. A win-win for both sides.
