I'm 75 as well and have been pouring jigs from 1/64-1oz, tying hair, Marabou and feather jigs as well as painting jigs for plastics for prob 40yrs...I enjoy reading articles here, suggestions from better fishermen than me but would enjoy reading or seeing instructions on modifying plastics both...
Really enjoy the tutorials from Jay...I've been trying for prob at least 50yrs but I still learn a lot from his videos and get some awesome ideas for jigs...thanks for sharing Jay.
