|I don't understand what you are asking OzA?
Yes I spot my belayer before he first clip I have enough slack to do so, as the anchors that I tie to are only a metre or 2 from the base of the wall... No I don't belay with my shoulder to the wall, that to me seems uncomfortable..
I get pulled into the wall when anchored, yes, but my feet hit the wall, not my face and I can only get pulled up as far as my anchor allows, obviously. The only way I could face plant would be if you get sucked all the way up to the first clip, This is what my anchor is preventing.. During the first few clips, indoors and outdoors, I am (as should everyone) extremely cautious of how much slack is out to prevent a ground fall and the position of myself to a) prevent being fallen on or hit with gear on their harnes, and b) to prevent gear stripping.... but thats another kettle of fish.
I'm baffled by your question OzA, could you rephrase it if the above hasn't hit the spot.. I tried my best
I'm not suggesting this should be the rule... not at alll. This is just what I prefer in certain situations... You aren't TOLD to tie down, it's about using common sense and judging the situation yourself.. IF you prefer not to be anchored, then don't...
