ScubaJo, I feel your pain. I finally broke down and got a DUI TLS350 recently. I've logged a handful of dives on it so far. There's definitely a learning curve. I think I'm OK with trim and buoyancy part. However, the ascending part still needs work ... venting suit and getting weighting right. I've also noticed my SAC has gone up a bit since diving dry ... need to factor this in to dive planning. Yes, it's been a bit humbling ... but so worth it
