Great topic Mark!

I have to agree with Matt and Rob on the net choice. I used to lose big fish at the boat when fishing solo because I didn't have a net. The big Promar net is a neccessity when fishing for big bass solo. I land all of my fish now :)

Spare treble hooks and split ring pliers for your swimbaits. I have bent hooks on a bait that is getting bit. No sense fishing a bent or repaired hook again because it will just bend out. Losing a fish of a lifetime sucks and you bet I will not reuse a hook that will bend again.

Handle the fish carefully like Rob and SWMB8R have told you. Its important to get the good brood stock fish back in healthy condition.

Use two hands when holding the fish in a cradeling type hold. I have to admit I have not done it all of the time, but I learned my lesson. Their jaws could be damaged from holding them by just the lower jaw.
