Flip side, I’m quite useful for standing on to give someone a lift up! I’m also normally warmer than others.
Hello Becky, welcome to the forum and welcome to caving
I'm the opposite, 5' 5.5" and under 10 stone. Problem I have is I feel the cold badly and struggle with some climbs as I just cannot blummin reach. Also, when I pick my bag of wet kit up (boots, suits, SRT kit, lights etc) after a trip am always surprised at how much it weighs - no wonder I get tired.
So cavers of all shapes and sizes have advantages over each other in different circumstances - we little 'uns are annoying in squeezes as we zip through, but as Steve says above we also need to stand on folks sometimes to get up climbs and the clattering of our teeth can get irritating
Re claustrophobia - I've never had a problem with this but am no fan of big pitches - what I find is the more I do them the better it is. I don't really remember the squeezes I had little problem with but I do remember in a positive way the big pitches I did
Good luck on your discovery of the underground, cheers, Pegasus
