I got the media in my +1 bag switched out, I share the same sentiments.
Pro's:
-Saves 10+lbs when it's on my ruck
-Gives me the option for another tool in my toolbox
-There was enough media in the PURG order to fill my +1 bag (which is huge IMO) and probably my Schmedium too if I wanted. I was worried there wouldn't be enough fill to get my +1 bag full. Worth noting a got a large bag from PURG.
Con's:
-It's just not sand and the bag still feels a little bouncy.
In all I think it's a combination of the +1 bag being new/not fully broken in and the difference in fill/media. I'm comparing it to my 4 year old waxed schedium that's been to the moon and back and it's just super worn in and it probably is 2/3 full of sand. In all I think the +1 bag is just going to be a good rear bag until I get it more broken in.
@Precision Underground can your fill be microwaved? I like to wax the outsides of my bags and then throw them in the microwave to warm the wax. Also, is there any detriment to the media if it gets wet?
