Its generally considered a good idea unless you don't mind losing some lures.
For macks / wahoo we usually use a few feet of wire connected directly to the lure at one end and the mono leader at the other. Some people use a snap swivel to connect the wire to the mainline, others tie direct (sometimes fish can attack swivels). From memory we generally use 60-80lb piano wire.
If you get a fish or a hit and the wire comes back all bent - replace it.
Learn how to hay wire twist the wire to make reliable connections.
I've just used mono for trolling and to date have not lost a lure (touch wood). Would hate to lose a big one due to being bitten off though. I've wondered about trolling two of the same lures, one with wire and one with mono and seeing what the strike rate is like between the two, my guess is there wouldn't be much.
I use mono and have boated many wahoo, spaniard and bills etc. I have used wire in the past especially on deep divers.
In saying all of this I lost the biggest spaniard of my life last march on mono. It was one of those things were he was looking up at me refusing to get in gaff range while he chewed on the leader. He did wink as he swam away, bugger.
I feel fish bite beeter on mono. Be prepared for the bust off.
An old pro once told me when trolling high speed lures he uses wire and slow trolling or pulling livies he uses mono.
At high speed the wire compared to mono hook up rate was virtually the same but at slower speed the mono hook up rate was far better but the loss of a few fish is inevitable.
