Reasoning is that I want nothing that can get hung up to be permanently 
attached to me . I can cut off comething that has no metal to metal connection.

 Some people thought I was discussing electrolysis - a good point for other 
applications - dissimilar metals will set up a little welding shop of their
own, 
as they are technically a battery in action, and make a mess. I just grease 
these things with silicone, like the tank to tank band interface, stainless 
screws to aluminum minterface, etc. Some tank bands used to come with liners
for 
that reason. You can also run a piece of electrical tape where the hose clamp
or 
band is going to go, and it will work, or paint the area first .

  The main thing is that if you get hung up, and this is more likely to happen 
in a wreck than a cave, where the current can come up unexpectedly, but it 
happens in cave - it happened to me in Wakulla of all places, and repeatedly in 
Big Dismal and Sally Ward - you need to be able to remove you stages no matter 
what, and you light no matter what (by the way this is another reason for not 
using a butt light, now we are up to Reason Number 19), and your reels, and 
anything else that could hang up. This is a good reason to have you knife on 
your belt where you can reach it and to have a hilt on it so you don't drop it, 
and to have a cerrated blade so it cuts the first time, and to carry a backup 
knife someplace, in your pocket, on you light handle, etc. 

   This is also the reason that I use velcro straps on my argon bottle - so I 
can free it myself or it will pull loose in an emergency. This is how I got
hung 
up in Wakulla and Sally, and how you can get "keyed" into a restriction (fit 
goining one way but not the other).  It was only a momemtary problem for me. 
   
    This is the reason I use stainless hardware -  it usually never jams, but 
there is a kind of sand that will freeze it that you can not see in the Florida 
Panhandle, and if you are stuck by that piece of gear, it should be possible to 
cut it free. 

    Like I said, wreck is where this really is very important, as in a four
knot 
current, even  a buddy like Jablonski may not be able to get to you.
