There are two keys to the procedure AJ photographed: First, the line must be taut on the spool before the double-ender is clipped in. This can be problematic if the line doesn't wind up in a way to make it easy to get to one of the holes (a reason why I prefer spools with many holes to ones with fewer). Second, the "gate" must be on the outside of the spool. If the double-ender is clipped in the other way, the line on the spool will open the gate.
 
That's a version of the usual cave way of doing the spools. In a cave you might have 3 or 4 spools hanging out your back, so it makes sense to have an absolutely foolproof system of storing them without fearing them coming undone. Any method which does not pass the line through one of the spool holes will at some point unwind given the right situation. There is no way to adapt the cave spool method to an SMB (and by this I mean keeping the smb attached all the time). To use a method like this one you will need to undo the spool and attach the SMB at depth.

There is a way to do it with SMB attached, I described it in my previous post.

There's 4 step by step pictures. Never an unraveling for me.

Thank you! I realized I clip off from the side of the string, I will try this way next time.

If the double-ender is clipped in the other way, the line on the spool will open the gate.

You also need to be sure that the line is wrapped in a way that it is difficult for the double ender to rotate. This can be accomplished by ensuring the line is very taut AND that the line wrapped around the spool blocks the hole a bit. With the gate on the outside, if the clip rotates 180deg the spool will easily open the gate and actually "eject" the spool and line from the clip.

This isn't possible with the gate on the INSIDE of the spool... though there's no way to catch and hold the line taut that way.
 
The gate will find a way to open itself up wether you put it on the outside or the inside, its just the nature of how much twist it's applied. That's why, the foolproof method is to pass the line THROUGH the hole as exemplified by the cave diver's method.

WhiteSands, I found a video that clearly demonstrates the best practices and still keeps the SMB attached. Is this what you were doing?

Could you describe this?
Tie a bowline knot at the clip-end of the line with about a 10-12" loop. Then tie an overhand knot at the end creating another loop... about 1-1.5" After rolling the line on your spool, run the line through one of the holes on your spool, attach the clip through the loop, wrap the line around the clip until it is fairly snug to the spool, then clip to the spool with the clip facing out. You have to use a double-ender clip.

This guy takes it a couple steps further... https://www.youtube.com/watch?v=4MqPNJA6eRs

That method isn't foolproof. If the gate opens and releases both the spool and the line, the line will unravel.
