I would like to get set up for prawning and crabbing. I would rather spend a few extra bucks and get traps that fish well and last, rather than trying to save a few pennies. From what I have read, it is desirable to weight your traps. If so, would I be better off getting the Ladner traps in the commercial version, say the 30" ones? Does anyone have any suggestions for a good quality trap? If I move quickly I may get a big stack under the Christmas tree!
