I like maiden betting as well but only for longshots, i never take anything shorter then around the $8.00 mark unless i am very very confident and it has the services of a top jock aboard.

I like backing maidens who have had 1 race where they finished way back in the field especially when they started that race under 15/1 or thereabouts, this also applies to maidens second up from a spell, you will be amazed at the number of long priced winners you get, i have one i will never forget backing earlier in the year at Muswellbrook, paid about $126.50 for the win if my memory serves me correct.
