Ark feedback wanted

[guitarpreston]

I see a lot of arks come up for sale here or fb etc. I know a lot of guys (myself included) try stuff and flip frequently. But what did it not do for you that a diff pack system did?
I’m pretty happy with my duplex light but considering an upgrade

Ark is a big upgrade to the DL for me. DL never felt right until it was heavy. The Ark is comfortable all the time. Lumbar and shoulder straps are big improvements as is the waist belt.

I cannot decide which I like better, the Ark or the K4.
