I'm 75kg and 6'2 tall, and ride (local shaper version of) a pod (6'1). Dims are basically identical to the CI 6'0 pod, just a touch longer.
Basically I bought it to replace a retro style twin fin fish, but now I ride the pod almost all the time, and almost never take out my shortboard anymore - including up to about shoulder to head high when the shortboard works well too.
The pod I got made was able to swap fins to be either quad or thruster, and after a lot of debating, I now leave it as a thruster, as it has better drive and hold with the wider shape of the board, so I'd recommend getting the thruster fin option. I just found as a quad that I ended up at the bottom of the wave missing sections, when the thruster set up gives me more drive to make the sections.
It is a lot more sedate to turn than a proper short board, but it is near enough for me to be happy with top and bottom turns to my skill level. Maybe if I was a better surfer I would push harder, but it's fine for my style, which is pretty relaxed. I think if you're busting airs, then get a smaller size, and you should get some of that response back, but I need the extra volume and early wave catching ability more
Haven't ridden the Gravy, but if you found the pod a bit skittish, a slightly bigger one is fairly settled in my experience.
Hope that helps.
