If your fishing on the bottom, heavy weights will snag. You can use light line on the weight so it breaks off saving your lure, but lead is expensive.
In the spring, I use dipsy's for lake trout and they work very well. The dipsy can be adjusted to swim off to the side of the boat which I believe helps.
There's a learning curve for a dipsy so best use heavier line. If you catch bottom you can usually turn around and recover it.
I've tried lead line for a couple of years but haven't caught anything to speak of. I've talked to guy's who use it and they say it works so I'm sure that it's my lack of fishing skill.
I did use weights for walleye but got away from it because of barotrauma. I didn't know about it and unintentionally killed walleye by fishing too deep. Not a problem if everything is in the slot size and your keeping it.
There's some mention on the web about fizzing fish by sticking a needle in their swim bladder to release air. I've never done it so don't know if or how it works.
Personally, if I was getting stabbed with large needle, I'd want the guy doing it to have some sort of diploma.
Here's a couple of articles on the subject.
