Grant, I can't remember the spec on the tracker, but in regards to heavy, that is a pretty relative thing. Not only to the person, but in how the person is carrying themself. If you are tromping in the woods with jeans, boots, pack, and a jacket, you won't notice it anymore than you would a KaBar even though is probably weighs +2x that knife.
I hardly carry anything unless I am travelling outside the SE, so it is a lot to me. In fact, I am going to try just carrying a neck knife.
Even though I don't carry it, I will say this, if I was in a wilderness survival situation and I had to choose one thing, it would be that knife (or the Beck WSK).
Oh yeah, the Tracker knife has a scout carry option (horizontal) which is nice, just don't fall on your back.
