The Master Pro kit would also eat up about a third my entire BOB budget... <img src="images/graemlins/shocked.gif" alt="" />

Seriously, I'm not out to find a single kit in a tiny size that does everything. I've had my hiking pack organised as a psuedo-BOB before. Mainly in the colder months when I don't get out there much.

My BOB kit is based on a small ALICE pack (smallest I could find), because I want to keep the weight down to about 10kg. And not be tempted to overpack... I've already got most of the essentials in there, and -any- one of these prepackaged kits is going to be doubling up on quite a few things. But that's exaclty why I'm looking at one, it'll be in there as a backup. Kind of a last-resort thing.

My problem with the partially-stocked-hiking-pack system is that at any given moment I wouldn't have been able to say for certain what was in it.
Expecially in the summer months when varied-length trips demand slightly different equipment. Sfuff would go in, stuff would come out, and apart from things like the Trangia, sleeping mat, tent and old camp shoes I'd never be sure what was where.
Sometimes there's a fishing rod in there, sometimes not, sometimes there's cold weather gear, sometimes not... etc.

After a couple of years of that I've had to admit to myself that I'm not dedicated enough to consistantly maintain the contents. (Ever come home from hiking, bone tired, and just dumped the pack contents on the floor to clean up 'tomorrow'? Well that's what I'm like...)

The idea with my BOB is that it'll always stay packed. I can load it up, and just keep it close at hand in case I ever need to grab it and go. Plus it'll contain stuff that I wouldn't normally take hiking.
The clothes in there will stay there (heavy duty stuff), a pair of broken-in boots will stay in there, the food is 3 days of MRE rations (plus another 4 days which can be added if time permits) which are WAAAAY to expensive to take on a normal hiking trip, it'll have a bivvy bag instead of a tent (haven't bought that yet either), and I have a far more comprehensive first aid kit set aside for the BOB than the one I normally take hiking.
Oh, and I just got a water purifier which I've never had a need for on my normal hiking trips.

That all make any sense?
