I believe that most
real(tm) knot tyers would sacrifice some ropelength, to tie a more convoluted but simpler, conceptually, knot, even if this might look as an overkill. So I think that, instead of tying the
6-wrap Double Cow hitch shown at (1), to avoid any thinking on how he should arrange the wraps along the pole, one should better make just another step, and tie the 8-wrap one instead. To the devoted believers, I would reply that, yes, it is nothing but a
double Prusik 
- but a
locked one ! So, if the Prusik appears tight to them, they should tie, try and see what this beast is able to do, when it will be properly tensioned.
"Properly tensioned" here, means only that one should tighten the wraps following the method I had described :
by pulling each end at a time, the one after the other. I have seen that this hitch continues to shrink, even after I had been pulling the one end after the other for 10 times ( each !
)( After that, my back refuses to serve my curiosity...)
I have only tied it around rather slippery poles and on rather slippery ropes, so I suspect that, on most "ordinary" situations, where the friction forces between the rope and the pole, on the one hand,
and between the adjacent wraps, on the other, is much stronger, it would be quite difficult to tighten it very much - but then, in such circumstances, the
Double Cow hitch would be adequate, I think.
