I have used the line & chicken neck before my grandfather had several large drop nets made. He had a fellow make them out of galvanized 3/8" cable and wove the mesh to them. Talk about working GREAT!! Baited the center with fish heads or chicken necks and lowered them in a likely crabbing area (we knew several in the lower Galveston Bay area) and always crabbed during a tide movement.
I haven't crabbed in a few years, but need to get out there this summer for at least a day as close to the full moon as possible (the crabs are much fuller with meat).
One of the best places I have crabbed in the past 2-4 years was the fishing pier at the old HLP Spillway in Bacliff (not sure if it is still there since the hurricanes). Another good spot is over at April Fool's Point around the marina and area.
Fatboys Marina on Jones Lake under the Santa Fe overpass by Tiki Island, their pier is pretty good toward the end.
Actually any location where you have coastal waters coming from the bays into a bayou or ditch with a good strong tidal movement, will have crabs, fish and their prey funneling in those waterways and are excellent places to try.
The water temperatures may be still too cold for any amounts of large eating size crabs to be moving but a few weeks to over a month should find them getting more active and feeding.
Just make sure the crabs you catch are at least 5" from tip-to-tip on the carapace to be legal and also they are not female crabs with eggs present.
http://www.tpwd.state.tx.us/publications/annual/fish/crabreg/Sorry, can't give you any results or recommendations on the Crabhawk, but it looks like the trap may have too large of mesh for blue crabs, but good for Dungies, might also be limited to how many you will trap once it's pulled up. The ring-type drop nets, large ones, I have caught up to 8-9 big blue crabs in a net during the peak of feeding and tide movement.
Good Luck!!
