i already have my Molle II BOB that i posted before, just got some birthday $ and it's burning a hole in my pocket .

I'll start by saying that i've been toying with the idea of dropping/selling the molle II set up as it is too heavy, maybe switching to the Rush 72 would cut down on a lot of weight, or just make another BOB for my Fiance and keep it in the car.  I have my fiance set up with a second molle II however it is about half the weight (25lbs) because she can't handle much more, and it has tons of room left in it, so possibly her using the rush 72?  

Just looking of opinions/criticism/thoughts.  I already have emergency cash set aside so i'm looking at spending the money

ETA for answer: i'll be using the bag for camping and hiking as well, when not in use it'll probably ride around the trunk rather than sitting in the closet

My opinion (worth what you paid for it) is that I hate to spend money on a bag that is going to sit under my seat all the time and (probably?  hopefully?) never get used.  This is why I use an older bag (left over from my last gear upgrade) in the truck.  My misc. truck gear (mostly tools/car-related stuff) is actually in a cheap duffel that also sits under the seat.

That frees up cash to use on stuff that I will actually use regularly.

Again, just my $0.02.

taggage.

I've heard good things about the Rush 72

Seems pricey for what you get.

Here is a SDS bag for $85.00 that got good reviews.

Grey Ghost has Tactical Tailor three-day packs on closeout right now, too.

There's also the Kelty MAP 3500 which has gotten consistently good reviews here and elsewhere.

For the price, I just don't think that 5.11 bag is going to be as quality as item as the above listed options.

wow, now that makes deciding really hard!

ETA: i really like the SDS, i like the kelty as well because of it's low profile but i don't think it holds enough

I agree, thats why I use LAPG 3 day packs (~$30) for BOB's that sit at home or in vehicles.

I picked up the Rush 72 to be my regular backpack, but I was able to fit everything I needed in without using the main big compartment It is definitely high quality but too huge for my everyday needs. I'm exchanging it for a Rush 24.

I'm having a similar dilemma.  Review of the SDS pack just went up here.

I like the low-profile look of the Kelty, too.  Read that gear review linked above––seems like it's a bigger pack than Kelty claims.

Also, like the above poster, the GHB stashed under the back seat of my truck is a cheaper bag.  Instead of the LAPG $30 special, I bought a used Mountainsmith 3,000 cu. in. pack off ebay for $17.  I find it is more comfortable than the cheaper packs, blends in better than anything with molle type attachments and now is the time to buy a used pack on ebay––it's not exactly backpacking weather at the current time.  

ETA:   Here, here, and here are some good examples of 2,500 cu. in. GHBs that will likely sell cheap and be more comfortable/durable than the cheaper LAPG packs.

Heh, just sold my Rush 72 on the EE for $95... It's a good bag but it got replaced by an Eberlestock. Basically a very large 3 day pack with excellent pocket organization.

I still use a Rush 24 as my work/GHB, and my son has one as his BOB.

I can't speak for the Rush 72 but I can honestly tell you I'm not seeing any problems setting up the Rush 24 bag as my BOB.  I'm also planning to use it with some ultra light backpacking gear on a week end hike to see how well its laid out.  But I'm also putting together a lot more essentials in my BOV (a deuce and a half for the record).  I figure if I can survive a weekend living out of of the Rush 24 it should work well for a GHB which gets me to the real stash and BOV.

I have a Blackhawk "Barrage" hydration pack and love it.
It comes with a bladder too

The 5.11 Rush 72 may be larger than you think (2894 in^3). For a 25lb pack on a small frame, I would go with a Rush 24 because there is going to be alot of empty space. Hell my school bookbag is 25lbs.

I bought the Rush 72 for my BOB / 3 day backpacking pack and it is large. I can fit: Sleeping bag, hammock, clothes, food, 1gal water, and all the trimmings into the pack. It's comfortable up to ~45lbs, at that point I would the go with a frame. I can easily make it a 5 day pack if needed.

I have the 72 hour bag and it works great. I keep all my day to day stuff as well as my supplies in it with room to spare. The only real issue i have with the bag is the back pocket is held on with webbing on the bottom and some small stiching. While the top is buckled on. This can come in handy when i want to store stuff or have an over sized load buckled in but hanging out both sides. But as a bob bag it can hold everything and more. Though if you can't handle the fact that its a little big you can always get the 48 hr.
