It depends on how often you lose lures, if you fish from the bank primarily, like I do, you are absolutely going to lose more lures than someone with a boat who can retrieve them, also don't forget to add in new hook/ring costs, I have a few cranks with dozens of fish on it, definitely economical, but I've also thrown $15-$25 jerkbaits and been broken off without ever having landed a single fish, which hurts my soul, I never get that feeling losing a soft plastic, they are intentionally disposable, even if it is fair to question the environmental impact of their large scale use on fish and fishery...I am not at all saying that one should never buy hard baits, just that unless you regularly catch bucketloads of fish on the same one, it's not very economical.
