That is my regular setup. I dive warm water, so very little weight required for my conventional hydros/AL80 setup.
Early in the chain someone commented about “blissing out” with Avelo. Well I bliss out every time without Avelo and have such a minimal weight with a conventional setup that I am skeptical it would have a significant kit weight reduction in my case. I think Avelo training aims for proper weighing the divers and they emphasize that in the e-mail response again. That is obviously important for any divers - Avelo or not. Years back I worked on getting my weight down to a minimum comfortable, I have little weight and very little air in the BC. With such a setup I do not see big advantages to Avelo (buoyancy changes with depth and weight reduction) for me personally. It sounds like it can be impactful for other divers. I have not found a desire to pay extra for training or rental of Avelo. I think I understand pretty well how it works, and wouldn’t mind to try it, but it is crazy to pay as much as it was described being charged for a “course”.
