I have never had a lot of luck with Top Water Bait's but I'm not saying they do not work,I to use Panther Martin's a lot myself I find any fish will bite at them,I like the Number 6 9 and 15 for larger fish.
Check out these Video's and what the one where he is catching Bass and the little trick he does with his finger it really does work and not just with Panther Martin's.I also find a stiffer your work's best with his finger trick as an Ugly Stik or a light action Rod does not give the same action,also make sure to use a Ball Bearing Swivel as these thing cause line twist,I also at the end of a day let out a lot of line behind my boat and pull it for a while to pull the twist's out or let my line out in fast water.
