when comparing a hauled with a none hauled cast, I think most fly casters would tell the hauled cast to be more efficient.
There are of course different effects having an impact on efficiency for both casts.
One effect/difference I yet haven't read anything about, that I have thought about for a while, I'd like to discuss.
When I pull my line into the first guide, (almost) at the same time my line moves 1 to 1 into the tip ring. That is momentum in the wrong direction for the line below the tip. This momentum has to be overcome by the line outside the tip, when I stop pulling line in and let go. So in terms of efficiency I have for example 10m line mass outside the tip moving in launch direction to then overcome the moving for example 5m line mass below the tip to line hand.
For a DT line I think this would be quite a large loss since the line outside the tip is tapered down... For a shooting head combined with a thin RL this would be much less of an effect.
In terms of efficiency this made me think about the perfect hauling length.
In my teaching though I always have been teaching:
Short line (outside tip) = no haul
Medium line = short haul
Long line = long haul
It probably would be more accurate to say low line mass instead of short line, since a short but heavy head can well be hauled.
Have there ever been made any calculations on the rates of momentum outside vs below (inside) the tip in relation to line tapers and line length?
Oh, btw. would you haul a static roll cast?
