Hard Water Bottle/Canteen And Carriage Options?

[Jellybean]

Looking for some options on hard (plastic, metal) water bottles, as well as carriage on gear (shooting loadout, pack).

I love camelback style water bladders- I think they're the next best thing since sharpened steel and gunpowder, BUT I have been doing some reading lately and it has occured to me that maybe they're not quite the be all- end all to water storage in the great outdoors, and maybe I should consider the addition of something more traditional.
It seems sometimes it can be easier to purify natural water with these, as they can hold hot water (like with a stacked cup ICW the bottle https://www.m4carbine.net/showthread.php?t=114195), or be boiled in and of themselves if needed. Can't do that with a bladder...

For hard bottles, here are some thoughts and concerns I am having;
I like the Nalgene type (32 oz, widemouth http://www.maxpedition.com/store/pc/...tle-76p468.htm)- cheap, and from what I've read about as indestructible as a plastic bottle can get. Doesn't hold odors.
Can get a CapCap (http://www.humangear.com/capcap/) to make use easier, while keeping the widemouth.
Cons- not very heat resistant, still ****ing (did the swear filter work?) plastic. Maybe not so good in cold weather, being plastic?

The oldschool USGI style canteens are pretty sweet as you can get them with the little metal cup-thingy so you can heat water and stuff.
Speaking of which, dose anyone have a good source to buy them complete like that, where they're not mauled to death or filled with 300 year old swamp water? USGI stuff makes me leery...
Dislikes- still plastic, narrow mouth is narrow... sucks for cleaning or inserting stuff. Holds odors[?]. Same other concerns as Nalgene.
Apparently Nalgene makes one (http://store.nalgene.com/SearchResults.asp?Cat=27).
Seems it's compatible with the USGI canteen cup, so I guess it's about the same size too.

Metal bottles- Have seen some recomendations for Klean Kanteen. Apparently their 40oz (http://www.kleankanteen.com/products...-40oz-wide.php) is about the same size as a Naglene 32oz. Their 27oz. looks interesting as well, as a daily or BB bottle.
A little more expensive (ok, like 3x more...) than the Nalgene/USGI offerings, BUT if they're that awesome, I'll take em'. AND there's currently a 20% off sale...
Apparently these can also be boiled by themselves if need be as well.
Cons- it's metal. Makes loud noises. Freezing in cold weather?

That's what I saw for bottle options that looked interesting, and have carriage options readily avilable.
Speaking of carriage options;

Want the ability to mount whatever hard bottle I go with to MOLLE.
Seeing a bit of a trend in this area, and there's 4 options I'm liking;

>Maxpedition 10x4 Bottle Holder (http://www.maxpedition.com/store/pc/...lder-7p574.htm)
>Hazard 4 Jelly Roll (http://hazard4.com/products/accessor...hes/jelly-roll)
>HSGI Nalgene Pouch (http://www.skdtac.com/HSGI-Nalgene-P...-p/hsg.214.htm)
>Maxpedition USGI 1Qt Canteen Pouch (http://www.maxpedition.com/store/pc/...OUCH-7p999.htm)

Concerns- pouches with rounded backs seem like they'd roll back and forth a lot when full and moving.
Sagging? Especially if the bottle doesn't fit the pouch exactly, or if all molle loops aren't engaged (like mounted to a battle belt).
Narrow MALICE attachment points- yay for there being two straps, but so close together, AND with a rounded back on some options? Hmmm....
Not sure if HSGI option is big enough for 32/40oz. Nalgenen/KK offerings?

Saw HSGI's newest offering their "Soft Taco" that can fit a 32oz. metal bottle. First USGI taco pouch I've liked, and would be good for BB use, BUT the 27/32. oz metal bottles in that style may be to tall, versus a USGI canteen, or standard Nalgene, and again, concerns with rolling/flopping/sagging.
Considering a USGI for BB use, as it's a little shorter (albeit, wide).

What to do....
What options are you guys using for bottles and MOLLE attachment that works?

I didn't know whether to put this here or in Tactical gear, so....
