I agree with NWD. My first thought when reading the 200 ft spool comment was that this could potentially be a bit wide to handle easily. 150' even strikes me as large and I agree that 100' makes morse sense for a safety reel as they are lower profile. I do have a larger spool, but I use it for shooting a deco bag in offshore diving, not in a cave.
In a cave I will carry 2 safety spools one in each pocket and each with 100' of line. I suppose if I get badly off the line in a really large tunnel and run out of line on one, I can just loo the end of the second one over the first and keep looking. Although to be honest, if I am searching for a ost line and come to the end of a 100' spool, I am first going to stop and assess whether I am seriously off track or searching down the axis of the tunnel.
Most of what you do with a safety spool is better handled by a 100' spool as under stress and in the dark doing a lost line drill or cutting your self out of an entanglement after tying in on both sides of the line you are about to cut, it is preferable that you have a smaller spool that you can control better and will be less likely to drop.

I am also a Larry Green reel fan. Ralph Hood reels are by the way also the exact same design. The side handle configuration used by the Larry Green/Ralph Hood and Salvo/Halcyon designs works very well with a goodman handle and is in my opinion lower profile and less of a line tap.
The major difference is in the philosophy of birdnesting the reel. The Larry Green/Ralph Hood design is very open with the philosophy that eventually you will birdnest even the most birdnest proof reel and it helps if it is easy to unsnarl under wate so they provide a very open design with generous clearances to help you untangle any birdnesting.
The Salvo/Halcyon design (also identical except for the brand name) uses a different approach with very tight clearances between the reel and frame so that it is all but impossible for the line to get caught between them and loop around the shaft. That said I have encountered people who have still tangled them up underwater and when that occurrs, tools are required to unsnarl them.
In either case, both the Larry Green/Ralph Hood and Salvo/Halcyon designs are well made with very nice drag/lock screws.
Personally, I prefer the Larry Green/Ralph Hood approach and in any case with a side handle reel if you snarl it on the way out, you can still wrap the line around the reel as you proceed out if you don't want to bother clearing it under water. The Larry Green design also allows you a couple different handle position options and a couple more options to control line tension with your fingers than the Salvo design. I also like the Lary Green design for gap/jump reels. They are smaller than the primary reels and fit easily in a pocket and also do not hang very low if carried on a D-ring during part of the dive.
However, I would still go with a spool for a safety reel application as you get a lot more line in a bit less volume and a spool is simple and idiot proof. About all you can do is drop it and have several loops of line fall off but you will never bird nest it.
I am not a fan of the Dive Rite reels, even though the newer ones can be set up as a side handle rather than lantern handle design. They have no real drag adjustment, just a lock that is slow to apply and they are much more fragile in terms of overall construction. They are not bad, they are just not great compared to the other reels available.
