From Lefty Kreh:
Gordy—for your info—-Jim Green was one of my best friends as was his wife Carol. He was instrumental in getting me to be the first fly fisherman to represent Fenwick rods. Jim showed me his pulley system and we used it—darn thing really worked.
To clarify the pulley was actually a roller guide such as used on big game rods. Jim attached it to a rod blank and held the other end in his hand to accelerate the haul.

[GH] Lefty,
As I stated before, I never saw the device or a picture of it. With your description, I can now get the idea of how it must have worked.
As part of my fly casting library/collection, I had a stack of Jim's and Carol's handwritten notes in a temporary binder. I made the mistake of lending them out and never got them back. The chap who borrowed them is deceased.

>From Bruce Richards. Lots to think about, here:
When distance casting, the most efficient point to start the haul:-
****Depends on what the caster is trying to accomplish. If max distance is the goal, then hauling as late as possible will slightly increase rod bend, hence tip/line speed. However, hauling this way is very difficult, if it isn't done just right the results can be negative. Only the most accomplished distance casters haul at the last moment. For our purposes in this discussion, lets say that this "latest possible moment" is 2/3 of the way through the casting stroke, that's close. For most, the goals are something other than ultimate distance and hauling at the latest possible moment is not the most efficient way. So, for most casts, starting to haul sometime a bit earlier than last possible moment is better, but how much earlier? Again, depends on the caster and situation. Starting to haul before the casting stroke (rapid rod acceleration) starts is counterproductive. It will pull a small amount of slack from the line but will shorten the length that can be hauled once the casting stroke starts. So, for most casts, hauling should start somewhere between where the casting stroke starts, and 2/3 through the casting stroke. Many, me included for most casts, try to start hauling just as the casting stroke starts. This makes the timing very easy and accelerating the line at the same time with both hands eliminates problems often caused by adding haul acceleration in the middle of the casting stroke. But, with practice that can be done effectively. There isn't one ideal time to start the haul for all casts.
The most efficient point to stop the haul on your false cast;-
*****This one is much easier. For most efficiency the haul needs to stop at RSP. That is essentially when a good loop starts (and hauling bad loops does no good). The rod tip and line accelerate to RSP, for the haul to be most effective it needs to accelerate the line to the same point. Stopping hauling before that (which is very hard to do) completely negates the benefit of hauling, and will most likely cause tip path issues (rising) and tailing loops. That said, I don't think I've ever seen anyone stop hauling too soon. Hauling past RSP pulls on the bottom leg. Pulling on the bottom leg, either with a haul or pulling the rod back, will force the top leg to turn over more quickly. Some think this might increase distance, but it doesn't. Top leg turns over sooner, which results in a more powerful delivery, but at a shorter distance. What do we all do when we've thrown a cast and know it doesn't have the energy to fully straighten? We pull back on the bottom leg to force the turnover. The cast turns over, but short...
Re: when the haul should stop, here's how I (actually we, with Noel Perkins) came up with the answer. We have a rod that is instrumented with both rate gyro (measures rod rotation), and a strain gauge (measures rod bend), and a haul analyzer (measures timing, speed and length of haul). In several casts it was exactly the same, when I hauled in a normal fashion, the haul ALWAYS ended precisely when the rod was straight, .1 sec. after rod acceleration turned to deceleration. When I teach hauling, I teach to stop the haul hand when rod deceleration starts, and students correctly feel the timing, and stop .1 sec later than that, without knowing it. To teach a .1 sec delay just won't work... Another instance of good instructors saying something a bit different than what they really want, to get the right result.
The most efficient point to release line from the line hand on your presentation cast;-
******For most efficiency, and assuming that the cast has been made with the right amount of force to reach the desired distance, the line hand should release the line just as the haul stops, at RSP. Holding on to the line longer than that has essentially the same impact on the cast as continuing to haul after RSP. Compared to releasing the line, holding it is like pulling on the bottom leg and will force a quicker turnover, but shorter distance.
