You could always just replace it with a bolt snap or a bolt snap with shackle. Either put the shackle through the hole in the handle (like they used to sell it) or tie a regular bolt snap on with cave line. Depending upon how paranoid you are, it would probably be better to tie it on with cave line so you could cut the link if the system is under tension and you need to free yourself (i.e., no metal-to-metal connections).
I agree that a double ender can be problematic but it is beneficial to be able to remove it when using the reel and I don't see how that would work with a bolt snap.
I use a loop of bungee cord and loop it around. Not that it cannot happen, but I've never had the gate open up and lose the reel. I've attached a picture. The bungee helps absorb the shock and reduces the likelihood that the gate is going to get pried open.

IMO, the bigger issue with the Dive Rite reels is the clearance between the spool and the cross bar (another picture attached). If you don't keep constant tension on the line, I've had the line "slip through" the gap and get fouled up. I don't know why the gap is so much. I could use a much thicker line, but that doesn't make sense.

I bought a Light Monkey reel because of this but haven't really had a chance to use it yet. See picture of the clearance / gap on that reel.
