Your right Silas and Grampa
I too been using the same worm. When I email jim he told me all Ztech (zman) plastics melt. Hes plastics are the real thing and they are 100% plastic with a addative in it. Plus I can use a 3/0 hook to make it float. But your right silas a 2/0 will make it float real high on a Caroline keeper. I like 4 foot leaders. and it floats like jim said. I asked Jim about melting and he told me the floatit will not melt with your other plastics. I try putting a bag togther and they have not melted yet. To me they are very flexable and catch couple bass on them like most plastics.
I went to youtube and found the trick worm jig head that floats with hes 7" worm. Here it is if you want to check it out. It looks like a cheap video but he makes hes point very good on hes baits.
