Replying to Head Thrasher v Full Tilt First Chair?

Im due for a boot upgrade after having the same boots for the past 6 years. Could anyone who owns/used the Head Thrasher 100 boots give me a bit more info about them. Do they feel heavy on the foot in the park? are they durable? whats the flex like? etc

And before the cries of go to a boot fitter, I've already been and was recommended 2 boots. The Full Tilt First Chair, and then the Thrashers. Both felt good but obviously its not easy to tell whether they really fit until I use a them out on the hill. Also I've heard bad things about the full tilts falling to pieces.
