Currently, I have my backup on a necklace. I would like to experiment with some different mouthpieces, partly because I do sometimes get that jaw muscle fatigue feeling after a dive. I've ordered the comfobite and the Manta-bite (which I am particularly attracted to given the reported safety features). At least for the Manta-bite, it doesn't seem like a good reg to donate. So I am thinking about putting that on the reg that's on the short hose (on the necklace currently) and using that as my primary. The question would then be how to attach the backup reg that would be on the longer hose. In my experience, I have not found any regulator attachment systems that I like (e.g., scumball etc.). Would there be anything too terribly wrong IYO about attaching the long hose of my backup to my tank with something like www.diveriteexpress.com/gas/retainers.shtml, such that the reg is sticking up over and near to my right shoulder?
