Lowe and DakineI have two, the Lowe Snow Attack 50 which I use for larger loads and which doubles as a lightweight weekend and mountaineering bag in the summer, and the Dakine Ridge, which at about 30 liters is the next step up from the Helipro. At 6'3" and 225lbs. I find need a little more room in my packs to carry gear and I also need packs that adjust to fit my torso, so I usually have to go a little bigger.
The Lowe has a large undivided main compartment which makes it very convenient for carrying a sleeping bag. The Dakine is internally divided and has full zippered access from the back, which makes it easier to find things for most daily trips. Both are hydration compatible, and have all kinds of external attachment straps and pockets for ski carry, shovels, probes, etc. They will also both adjust to fit a 21" to 22" torso size, which is not the easiest thing to find.
Both are great packs and I would recommend either.
For most days inbounds I will use my parka pockets and or a fanny pack (yes, you read this correctly) which can handle most of my requirements if I am not going to do anything too exotic.
