Rohan, if your fishing from a boat, consider looking at a lure retriever. I have a strickeback lure retriever from Strikeback tackle and it is amazing. I was losing a dozen plus heads a session in my local water until i got one. Now im unhappy if i lose three to snags. Obviously the smokings from fish dont help but i sure have saved money on jigheads since.
You have to love the good old round heads, they go with anything and always produce. I used the size 4's today for smaller plastics as the fish just didnt want to look at larger ones. They never cease to amaze me.
