I've done a few things regarding hardbaits lately. 1st, I've done completely away with treble hooks...I've gone to singles. 2nd, and I'm waiting to see if this is going to bite me, is I've been using 3"x5" 4-mil bags to hold a few baits each, and pack these in their designated spot. I've noticed through the years that the finish on loose hardbaits will decline as the bait rolls around, and rolls around on treble hooks. Packed a few baits per bag, they don't roll around. I also don't fight a Wad of Hardbait/Treble-Hook DemonDough.
This will, however, take some diligence on my part. I have to make sure they're rinsed with clean water after the day's over, then completely dried and bagged, to try to avoid rusty hooks (I despise rusty hooks...they're also weakening as the rust progresses).
