wingnuts or reg. nuts and backplates?

[roakey]

Wingnuts is probably more of a doubles thing than a DIR thing. When we swap doubles the wingnuts come in more than handy. If you have a singles setup I don't see any problem with a nylock nut since you don't have to take them off to swap cylinders.

and here is my answer to myself:

I am on a boat dive far from shore and everything turns to crap. I surface far from the boat and hours pass. Now I want to ditch some gear but at the same time retain as much as possible that MIGHT be useful. Let's see ... my 55lb lift wing MIGHT be useful flotation but I need to separate it from my tanks.

Damn. I used a regular nut ... If only I'd used a wingnut ....

Anyway .. that's my reason and I'm sticking to it.

p.s. also, if you place a weight between the tank and the BP you'll probably find that "just the right length" bolts become "too short"

I agree with you on the BP weight. You would have to allow a little for that. I have looked at some Dive Rite weights. They appear to be a shot weight and the grommets wouldnt take up much of the bolt. A solid bar would take up more. Unless you recessed that hole some.

I dont buy the ditching tank thing though. If Im using alum tanks, I can bleed air from them and now they float. I can disconnect tanks from a BC and ditch them a hell of a lot easier than taking apart a backplate anyway.

My Halcyon MC system has a backpad secured my 8 small screw/bolts. You can access one wingnut just fine, but try getting the bottom one off without removing the pad. I can do it on dry land in my chair at home, but I wouldnt count on it bobbing on the surface.

Don't connect the bottom two bolts. They aren't needed and make accessing the pouch harder besides.
