A suggestion: Save time and get the Torpedo Bait Bucket. $40. 0 drag. Super, super light. Holds about 5 huge macs, more medium sized ones, and a lot more small ones. In all my trips all bait survived and thrived. Check it out:

Buddy gave me his DIY one before I bought the Torpedo and found it too bulky and heavy. He actually ordered one too even though he's got the Hobie tank.
