Is it worth it to switch from Osprey Atmos to Exos to save weight?

My wife and I started hiking this season (we have been cycling for 10 years before that). We have pretty light and compact gear, except for the backpack. We carried Osprey Atmos 50 and Osprey Talon 22 on a week trip. Everything including food and water fit in nicely. Base weight of the 50 liter pack was around 7,5 kilograms and it was about 15 at the most with the food and 5 liters of water. Now I am considering to switch to Osprey Exos for the next season to save additional 500 grams.

My concern is the suspension system on the Exos which seems to be less comfortable than that on the Atmos. I already had some discomfort when carrying 15 kilograms in the Atmos. I am concerned the weight saving might not be worth it.

Is 500 gram weight saving significant? How noticeable is the difference in comfort from 500 gram weight saving?

I have another crazy idea - bring the Atmos to the local workshop which mades my bike bags and let them replace the heavy fabric on the Atmos by a lighter fabric. But I would prefer not to do that.

Update: We hike in northern Europe, temperatures 10-20 degrees Celsius, 5 days without a resupply (at most), water has to be carried for at most one overnight stay. Winds up to 35 m/s, but rarely. No snow. We hike in trail runners and most of the gear is already reasonably light. Our combined base weight is about 14 kilograms (for two persons).
