I think my comment in post #43 sums up my feelings
Delboy99 and I also think several people have mentioned that if the bet was viable someone would have come up with it by now especially as traders on Betfair (well some anyway) are pretty fly and would have surely cracked it by now. Others have tried different angles (see Toms post top of this page); I don't feel that any of us are disinterested as such, it's probably the lack of any more real info to go on - which is where you can come in; what you say in your post is a truism - there looks to be just the two bets required there i.e. not a true Slicer bet at all, just a means of trading a match using those two markets. Maybe some further research on your part may turn up a real nugget of information?
I am aware of that item from Soccer widow from some time ago, in fact Tom's first post on this thread reignited my re-finding it.
We all (or at least I do) have half a dozen football and a few horse racing systems that we follow and have keep track of so time is unfortunately divided up between them.
If you find anything further I'm sure people will be able to respond likewise.
Slicers bet has certainly become the stuff of legend now.
