The Grivel plume is great for a locker. On multipitch my only regular sized locker is the belay locker and the rest are plumes. They work great and hold a clove just fine, especially paired with a Mammut serenity.
What I am doing now on some trad draws is have a compact biner for clipping gear, and a larger, yet still light-ish biner to clip the rope to. Some people are OCD and need the same stuff, but I am more franken-gear at this point.
Most of my alpines are camp Nano on one end and Camp Photon on the rope end. So you're not alone.
