Jigging blackfish

[FlukinFun]

I am very new to jigging BLACKFISH. I recently fished the entire day with the same jig and had no keepers just two shorts. I would usually make changes but I felt like I hooked a really nice fish early in the day but dropped it so I stuck it out with the same jig. After the day I beat myself up about not changing anything. I felt I should have went to a lighter jig. Talking to a friend who jigs quite often he said,"If your jig hits the bottom every time you lift your rod tip and then drop it down, you are fishing too heavy. You should barely feel the bottom." Any opinions?? I would really appreciate your feedback.
