Moving to primes, should I sell the 16-35 or the 24-70?

So the issue here is weight? I'd like to offer an alternative opinion: Start an exercise regimen that will increase your overall body strength. Two days a week with weights, two days with cardio. I know it sounds silly, but not only will you have more endurance and better health, you won't notice the heft of those lenses so much.

Just my alternative .02
