There are several model 11's and a few of the model 10's. There is a Model 10 called Predator Hunter. It is completely covered in camo. It is obviously set up for the Predator hunter. The 11 series is called the Hunter. Since it is a hunter, generally they come with the handier 22" length barrel and lighter weight barrels. The lines between the models is very blurred. If you want longer (and heavier) barrels you should look at the 12 series. The 10's and 11's are lighter, making them easier to carry. The 10 Predator Hunter has a slightly heavier barrel they call "Medium-Contour" but it is still 22". It is also set up with the 1.5 - 6 pound Accutrigger. The standard Accutrigger has a 2.5 - 6 pound range. After doing some more research, it looks like the model 10's have a slightly heavier barrel than the model 11's, but do not quote me on it.
