Good idea, was thinking about this myself some time back.
I got four today on the National, more than ever before: Ballabriggs, Seabass, Synchronised & Planet Of Sound.
Had £8 lying in an online account untouched, so basically all in, evenly split each way, hopefully something good comes!
Mum was in the bookies early this morning and told me she would pay for a single each-way bet, chose On His Own, so that makes five!
