I have sold a couple of the HOG setups recently and have sold and set up over a 100 of them in the last several years for customers. I have 3 of the HOG wings myself on a standard plate, freedom plate, and the HOG comfort harness. I was selling so many for a while that I had a custom stand fabricated for threading the harness. I can pretty much set up a rig in 15 - 20 minutes. Give me your height, waist, and chest measurements and I'll have it adjusted so that only a tweak or two is needed. That will take an extra 5 minutes.
I used to dive a 23 lb also. The difference in drag is negligible. The other consideration is that the HOG 32 now has the bungee on the side facing the diver as an option for those who think a couple of inches make drag an issue for the average diver. Unless you are in wicked current or swim like a torpedo, drag is overrated. The bungee does make some difference though when the wing is deflated without affecting the effort to inflate it.
