I have an Advent Pro, it wasn't my first pack, but it has become one of my favorites.
I use it on solo trips during the warmer months.

I agree that it does have a lot of bells and whistles, but i like finding ways to use all of them.

I find that the "helmet pocket" can be used to store chacos or keens for river/creek crossings. i dont like to cross in my hiking shoes/boots.

If you have light gear, go for it. It is a pretty light pack and is very comfortable if packed well and not overloaded.
