Does anyone have any experience with the Apeks WTX system? I have one arriving shortly but due to a few logistical considerations, this LDS is about 4 hours away and I was unable to take a good look at it in person. Any one have experience with their sure-lock weight system? I believe Apeks was bought by Aqualung so the weight system could be the same but I have not used the Aqualung system either. Furthermore, do you know if the BP actually fits inside the harness back pad or on top and should I use the plate for singles even though they say you don't need it in the event you just use a single tank. I would appreciate any comments from those who have some experience with this setup. I want to keep the setup as streamlined as possible and use it for some extensive travel/diving and also Northwest cold water/drysuit diving. Many thanks.
