Molly....
You did well on this little quiz. Your answers also serve to highlight some different ways of looking at planes and pathways.
1.) I like to look at ROD PLANE as the orientation of the rod from vertical to horizontal ON EITHER SIDE OF THE CASTER.
2.) & 3.) The LINE PLANE, as I see it, is exactly as you answered. It's the path taken by the line which is the same as its TRAJECTORY. For example, we might have a high back cast and a low forward cast or vice-versa, attempting to keep approximately 180 degrees between the two for most casts. I have used the term, CASTING PLANE as a synonym for this, realizing that others such as Jason Borger have used it to mean the pathway taken by the hand during the cast.
I have embraced Joan Wulff's teaching that the path taken by the hand during the cast is a definition for the CASTING STROKE.
4.) through 8.) Correct. No discussion needed.......except to refer to p 121 in Joan Wulff's book to get the concept of, "long cast trajectory".
9.) In physics, the word, INERTIA is used to express the concept that things at rest tend to remain at rest, and things moving tend to remain in motion.
As you point out, the resistance of the line which is hardly moving at all at the end of the pause provides resistance to the accelerating rod tip. Thus the rod bends and becomes loaded as latent (stored) energy builds up in the rod.
It works in the opposite direction, too. For example, as the rod comes to a stop, a heavy reel will provide inertia since it tends to keep moving. That's one reason to consider a light weight one.
11.) You are correct about DRIFT. I'm glad you added that it can increase the available casting arc for the following forward stroke. (Also available stroke length.)
DRIFT has also been considered as the opposite of CREEP, since it is motion in the direction of an unrolling loop, while creep is motion opposite the direction of an unrolling loop.
12.) FOLLOWTHROUGH is the same kind of powerless motion as DRIFT, as you stated. It does go in the direction of the unrolling loop.
Joan Wulff has used the term, DRIFT to mean that motion following the back stroke, whereas she considers, FOLLOWTHROUGH as a term to describe the same thing immediately after the forward stroke. That's how I've been using the term.
I'll wait to share this with the Group until more answers are in.

Answers to Gordy?s quiz from Molly Semenik
I need clarification on Line plane and casting plane.
1.) Rod plane. The orientation of the rod from vertical to horizontal.
2.) Line plane. The path the line takes during the cast (Borger)
Trajectory of the line. Also called the casting plane (Gordy)
3.) Casting plane. The pathway the hand travels (Borger). Casting
Stroke, The path taken by the hand during the cast (Gordy)
4.) Trajectory. Fly line plane
5.) SLP. Straight Line Path of the rod tip.
6.) RSP. The position of the rod tip at the point where the rod is
straight, and the loop if begins to form as a result of the line just
starting to overtake the rod tip.
7.) Counterflex. An instantaneous bend in the rod immediately after
the RSP
8.) Rebound. The return of the rod bend after counterflex
9.) Inertia. At the conclusion of the pause, after the casting stroke,
the lines momentum is exerting force against the rod tip, flexing the
rod tip. The next cast must be timed so the line does not lose its
INERTIA and start to fall. The caster should feel the line against the
rod tip, inertia loading (Borger pg 68)
10.) Tracking. The path the rod tip takes.
11.) Drift. Drift occurs after the stop, drift is powerless. Two
benefits: one, improves timing by moving the rod tip with the unrolling
line, the caster will feel and know when to begin the next cast,
staying connected to the line. Two, the drift gives the caster the
opportunity to reposition the arm and rod for the following casting
stroke often increasing the available casting arc.
12.) Followthrough. Same as drift, rod tip moves in the same direction
as the line. Or, the lowering of the arm and rod after the stop to
present the fly to the target.
