Hi CharlieMack.
I have the Fastpack 40 (not Fastrack!), from a friend who didn't like it, which had been given to him by a friend who didn't like it. Neither liked it because it didn't fit, but they were both at least 4" taller than me. I'm 5'7" and it fits me very well - in fact I find it extremely comfortable.
It's a simple design, eats kit very well, and I've abused mine seriously for years with only a few scuffed bits of fabric (and the occasional small hole in the wand pockets which are less tough so I've put my walking poles through them a couple of times when storing them). Despite Lightwave's claim (if they still make it), it's not waterproof, and I wouldn't say it was any more water-resistant than any of my other tougher rucksacks, but I don't really expect rucksacks to be waterproof anyway.
