HARRO HUNNAYYY
I'm currently a DM candidate and dive a Scubapro Ladyhawk (women's version of Knighthawk) but the shop's rental fleet is Aqua Lung. The shop sells both. Before I purchased my Scubapro Ladyhawk, I was also considering some Aqua Lung options. I have been working with students regularly and I am not a fan of the Aqua Lung weight system. It isn't as secure as Scubapro's and does not give as large of a resounding click and assurance in my opinion. We have had quite a few accidental dumps and trouble with the weights from all levels of classes from OW to Rescue. We've lost some as a result.
I would also steer you away from the i3 version of any of AL's BCs for the reason that @SOFDiver mentioned as far as reliability/maintenance/failures. I got the same feedback from a student who owns an i3 product and had an issue with it. I have also witnessed accidental inflates and deflates when it catches, albeit on a boat during my travels. I was attracted to the i3 as well when I was shopping because of the convenience, especially being able to dump air from any position.
I am also more partial to a back inflate because I like not having the bulk around my sides and front but also because of trim reasons. As for parts for life, I don't think the BC matters as much as the reg as far as racking up bills for the kits so in my mind, it isn't enough to move the needle. I think you should go with what feels the best for you but I have a much stronger preference for Scubapro for the reasons above. It looks like you've had some good used options presented to you - awesome! Great prices.
I would stay away from an Air 2 but that is another conversation. If you want to hear about it...let me know.
