Stirke Zone - I have had several types over the years, and for the money I think the standard folding ones with four doors work best, especially if you pull them regularly and don't leave them overnight (the crabs seem to get out after eating the bait). I have a triangular "crab house" type trap and this one regularly under-fishes the folding traps. Last year I bought a really beautiful (and expensive)commercial-style trap made in Brinnon, stainless doors and a very large central bait holder. This trap was very sexy but didn't catch worth a damn! Somebody finally stole it(good luck and good riddance). The folding pots outfished that trap 10 to 1. I figure the crabs are a lot more comfortable entering the folding trap doors (rather than the funnels), perhaps because the doors are flush with the bottom? If your gonna leave the traps in overnight, the commercial-style traps might be better (because the crabs can't get out), otherwise I'd go with the folding traps.
