ICD thanks for posting this report. Being only cavern certified I haven't given a great deal of thought to multiple reels. My thought being that since I am only in the caverns right now I shouldn't need more than one. After reading you posts I started giving the need for extra spools some thought and have decided that I will be purchasing and carrying at least one more and maybe two. After all it doesn't hurt in the slightest to tote some extra gear when its that small and I definately never want to find myself in a situation similar to yours. So your post has at the very least helped a newbie keep from making the same mistake.
