By smoke grey I'm guessing you mean Lexan. Yeah that stuff is extremely tough. They do make both wide and narrow mouth versions. I've always preferred the wide. Never wanted to drink while running. I've never understood the popularity of hydration packs either. I don't mind stopping a few times an hour to drink from a bottle.

That all said, I have a 1 liter Lexan bottle (rectangular wide mouth) and it's great, but I usually just use bottled-water bottles. They're less tough but they weigh less and I just recycle them when they get beat up.
