In my tactics, I use an advanced forward and I have never considered target man and it doesn't fit my tactics anyway.
I also don't use pass into space since I like a patient play style.
A few days ago, I bought an English regen with insane physicals and the main reason why I bought him was because a weakness in my team is that we never win headers close to the opponent's goal in open play.
This regen, Adrian Smitheringdale is more then just a physical beast, he also got 20 off the ball and 17 finishing.
In a friendly, I decided to make some changes to utlize his strengths. I changed his role from advanced forward to target man on attack. My idea was that my team would look to pass it more to him. I also added pass into space on my TI's and I gave him instructions to roam from position and run into space. In that friendly he scored 4 goals before getting subbed off.
It was just a friendly, but I think that if you have a player like this, target man attack would work well.
