what i prefer is headfirst , either belly down or on the side.......but, in a really "dodgy" spot i always go feet first on my back,..........i can keep my nose closer to the ceiling when on my back than i can whenever i am on my belly or side......i can look down easier than up, and also see the waves coming, the helmet is off, and what you ask is the main reason i like to go feetfirst?.....well, if my feet get in trouble my head is concerned and still able to act because i can still breath and i am close to the larger passage and its a shorter trip out of trouble!!!....on the other hand if my head became fatally stuck my feet would flail uselessly untill told to stop or pulled forcefully by my friends!!...........i do however hate the way the helmet and light takes up one hand and the gear the other whenever going in feetfirst!!..... ........ 8) :shock: :?:
