I've been using a jacket style BCD I bought second hand 10 years ago and am ready to upgrade. While this has served me well, I find the style a bit constrictive and wanted to try out a BCD. I do mostly local shore dives in south Florida, occasional boat dives and very little travel diving - and then it would be warm water. I dive AL80 usually with either a 3mm wetsuit with 14lb or just a rashguard with 12lb depending on season. I've read through many BP/W threads but am a little concerned with using one for beach dives due to chronic thoracic back pain from an old injury. A dive buddy of mine uses one and says that its great in the water but does become uncomfortable for him when walking to and from the water. Are there particular styles or set-ups that may be more suitable for me to try? Even with my current BCD, I get a little pain when walking but that is due to the weight of the tank so I am unsure how the backplate will add, if any at all.
