Does anyone have pictures of there Crab traps set up

Hello I know there is some more crabers out there and I have a few questions.
  First do you tie riging to all 4 corners of a colapsable or just the end
  second do you add any sort of weight to the bottom of the trap
  Next do you hang a bait hook from the bottom or the top and does this interfere when in collapsed mode
  do you ese those bait balls with holes in them
Thanks for the input I have caught crabs a lot in the past but alway from a boat and never a collapseable trap

I have set and been successful with hoop nets for crab in the Tomales Bay area, but have never used any kind of trap.  Once set up, i assume the "collapsible" traps stay set up until you want to collapse them for transport and  storage.  But are there any tips, tricks, best practices for using them - especially as opposed to hoop nets?  Thanks.

BTW there is a great article on kayak crabbing in general:
