While the Sendero is not what it once was, it is still the hands down better choice of these two. I wouldn't give two pounds of powder for an Accumark.
I packed a Sendero around a couple of weeks ago on a sheep hunt and it wasn't that bad. Of course, it's weight was well spread out over my shoulders in my Eberlestock backpack
but there was a ton of other stuff in that pack with it too!
