"Suitable"? That's the method I use to get up muddy inclines of 45Â, because
that way I don't have time to slip.
I did not use the word "suitable".
ARGH! Sorry! "favourable".
And I'm not sure what your point is, unless you want to claim you can run up a 45deg incline on *any* substrate, including, for example, wet smooth ice.
You'll have to ask Don about that.
