Dual packs are awesome if you need storage space for extras or want to stuff a hoodie or something in it.
The problems rescue mention are legitimate. The discs rub coming in and out, it's not that big of a deal, it's just a pain in the ass.
Drink holders are non existent on the dual pack. The problem he mentions are only on the dual pack lite, the normal dual pack doesn't have a drink holder. Plenty of room in top to carry as much water as you want but once again, pain n the ass. Expensive DG bags probably should account for a water bottle.
No putter/mini pockets. I use one of the side pockets but once again when deciding to make high end DG bag seems like the thought " I wonder if it needs a putter pocket?" might have come up.
Top compartment sags down. Loaded or empty, the revo looks like a deflated balloon unless you find a way to make a floor for the upper compartment. It's easy to fix, but just another thing to deal with from a bag that's supposed to be the last you'll need.
Great construction, great storage, but it has some flaws that seem like design was overlooked. Still if you need storage this is one of your better options.
If storage isnt an issue, grab a grip.
