Got my Mystery Ranch Golf Mahal in the mail last Thursday.
I used it friday night for some night golf, saturday afternoon, and sunday all afternoon. I carried 22-24 discs, towels, drinks on both sides, and a golden retriever.
Most peoples first reaction was "wow that bag is huge." Granted I did have the sides pushed out to their max capacity, but it is doesn't feel any heavier than my revolution dual pack. The weight distribution is great, it felt like I could wear it all day for a 4 day tournament if I needed to.
The instructions they provide with the pack are fairly easy to understand. They basically tell you to have a friend help you fit yoke system to the right level on your back, so the pack rests comfortably to the shape of your shoulders and back.
I showed the guys at the night mini on friday what all the bag offered. Capacity, comfort, drink holders, umbrella holder, rain flap, and adjustable straps... the typical response from the local disc golfers here was "wow that has everything you would want in a disc golf bag." I tend to agree with that response. I am very happy with this purchase, and hell.. you just can't beat a LIFETIME warranty. So if you can afford to spend a few extra bux and you want something that is tournament ready. I personally would recommend this bag. I can't see myself ever needing to switch.
Oh and for all you disc/gear vultures out there, no you cannot have dibs on my old revo dual pack, as I am selling it to a friend here in town. Haha! Lemme know if you are curious about anything else on the bag.. I have only tested it for 3 days, but it screams quality so far.
