It's a great disc for thumbers or if you are not able to throw grenades. This disc stays upside down for such a long time that I'm able to throw a thumber that will travel left to right  quite a bit. It's gotten me out of trouble a couple of times. As for throwing "grenades", this disc is so overstable that throwing it on a spike hyzer it acts like as if you just threw a grenade. It goes up and straight down. There's a reason why this disc has a +3 rating from Discraft.

I thought that this disc would replace my XXX but man it was far more overstable than that.  When I first got it I couldn't get it over 200 BH or FH but as the plastic beat in (it does not do well with trees) it became more manageable to where I could get about 280 or so on a decent throw.  If you are looking for a mega meathook than this is your disc if not don't even try it as you will kill you arm trying to throw it.

I'm not sure how the standard Tracker flies (I have honestly never met anyone who actually bags one) but the Limited Edition Tracker sold to support the Ledgestone Insurance Open are crazy overstable. I can't say much about the glide, because it wants to hook up right out your hand. It feels just okay in my hand. Pure utility.

The ledgestone tracker is an amazing thumber/utility disc.  Super over-stable.
