I tried to narrow the holes on ours assuming most catches would be smallMason catches em all the time. We usually catch more in a minner basket w/white bread then we do in the actual crawdad traps. They are good eatin..but man it takes a bucket full to make a mess
Let us know if you figure it out, i saw a few bigguns in my creek this morn. I may run both sizes close to each other to maximize my catchI have tried it with very limited success. I actually think I'm doing too long of a soak as they will get out when the bait runs out.
