What kind of reviews are you interestred in ??

We head out once in a while to test our gear, and we take pictures and stuff.. and I would be curious to hear what kind of reviews, pics, testing, etc people would like to see us do to our gear

We typically weigh it and use it, but I bet there could be other tests we could do too

What would you like to see?
