Wouldn't that be due to the slack line in the piled anchor though?
Instability in the forward traveling loop can come from the anchor not being aligned to the target.
If the anchor picks up from the water at say 90 degrees to the target it manifests into a wobble (or side to side motion) as it feeds into the top leg of your loop. This can often lead to the fly landing above or below the unfurled line.
A wobbly loop inst as efficient and neither is the fly landing somewhere you dont want it to.

Hi Paul,
My first spey casting lesson was with Peter Mackenzie-Phillips, the king of the crashed anchor!
I always remember him saying, "just dump the line in the water, say your name then give it a good hoofing" - its purpose was to make sure you had an anchor and it wasnt skipping off somewhere behind. The rods them days were slow enough to still deal with this - how times have changed.
They've certainly changed alright. The level of single handed Spey casting has increased in the way that 5weight distance casting has in the same time period. No doubt DH casting has as well. Great stuff. I really have to work to stay current.

It is pretty obvious, I think. :p

it shouldn't be too hard to understand that we're not on the same plane... :p
if i asked, it's because i don't understand
Since some spey gurus say that piled anchors produce more line stick... most probably that chain experiment is just an illusion.
When the "anchor" is straight the hanging chain is pulling the whole length of that "anchor", and that resistance is enough to prevent gravity to pull everything down. When you pile the "anchor" the piled part isn't in tension, in fact the hanging chain is pulling a shorter piece of "anchor", so the balance between forces gets broken.
Aitor is not like us, he is Spanish, and therefore completely mad.

I'd say both: a mass that is motionless wants to keep like that resisting any change. Friction also opposes a resistance to motion.
What I wanted to show is that the same lenght of anchor subjected to the same force has different anchoring capabilities, depending on it being straight or not.
On one hand we have that a piled anchor opposes less resistance to the travelling D-loop; on the other hand we know that a bloody L opposes more force to the travelling D-loop, and a piled anchor has some slight traits of a bloody L configuration. So...

My experience with the bloody L anchor is the corner of the L sometimes scoops water, expending the loops energy into moving water than moving the line.
Perhaps with the pile anchor, anything with a radius can also scoop water similar to the bloody L. And perhaps for this reason why it is deemed an cast killer.
However, there is a anchor technique where the apex of the V loop is deliberately crashed into water as the anchor. Because of the apex of a V loop represents a small submerged area, the scooping effect is not so much that the V loop anchor feels almost the same as a regular leader anchor. The fly never touches the water with this V loop anchor, a boon for lip flies.

Aitor, will you set up the same experiment with the chain as a bloody L and with the chain gently curving away to the side?
can you explain why it is 'anchored' less even though contact surface is the same ?
