Longboard or big volume shortboard

Hi folks, I've been using a 9' mal for a while now but don't really like it that much. I've been kitesurfing for 15 years and SUPing (sorry) for a while and am happy enough with my wave riding ability. I just find the long board a pain in the ass to do anything on and to manoeuvre and to get through whitewater etc.
I've been looking at a few short board designs with higher volume (in the 40's) that allegedly paddle like a longboard (according to salespitch) and I was wondering if it'd be easier to manage and more enjoyable. I want to start surfing a ew smaller reefs this winter and thought a shorter board might be more suitable to the steeper waves. I have the SUP for the beach breaks and small summer days. I have average enough paddle fitness, swim regularly, body surf etc.
Anyone else out there go that route instead of the longboard. Maybe I'm just looking for an excuse to add to the quiver
