Thanks for clearing that up MR J , thats what i thought. you can aslo have line and start betting at some sites EG:

line. carlton -20.5 @1.90, melb +20.5 @1.90
start.carlton -25.5 @2.10, melb +15.5 @2.10

they adjust the line with the fav giving more start and the outsider getting less for a better price. so it can get confusing for someone thats new to it.

cheers
