should i?

So should i sell all my mhl shares (they are not worth much) and bet them all on the AFL grandfinal next weekend? It would begin to help me recoup some of my loss. I would probably buy back in for a punt when the saints pull through :p
The only reason i would consider this is i cannot see the share price rising significantly in the near future.

Any thoughts on which bet to undertake will be considered. I think a multi with sandilands on best player in freo going into the sometething else.
