Hi all, I'm sorry if this question has been asked countless times already... I have been renting jacket BCs (non-back inflate) since my OW classes and am now considering going BP/W (more minimal, better weight distribution, easily customizable). I've read numerous posts mentioning the benefit of having an instructor or someone familiar with BP/W to make sure you have the rig secured properly on you. Aside from that, is there a significant learning curve to actually diving in a BP/W if you've only dived jacket BCs? None of the LDS rent out BP/W (at least none that I've found), so I'm tempted to just order a complete rig from DSS. Should I expect to have a tough time diving a BP/W the first few times, without instructor/DM support? Thank you in advance for your advice!
