Chrome, I've always valued your opinion as you know. The only way I can see of backing shorteners is to stipulate a minimum price, i.e. $100 win X @ Top Fluc, minimum price accepted = 2-1 (or whatever) problem is I don't know how long the bookie would take your bets? and of course you could just as easily be backing drifters.

It's a pity theres no Betfair here in WA though, so many more options..... maybe one day!
