Hi everyone, Dirk here and new on the board. Sorry for the long post to start with but i hope its worth it.
I was inspired pursue fly casting more on its own (nearest decent fishing is 2+ hours away) after a demo with Peter Hayes on his visit to South Africa a few months ago. Turning into a geek...
Watching video on distance casters I’ve been intrigued that often a seemingly small down-up flick of the wrist could be seen right around final rotation on the forward cast. Sometimes more like just an “up”. Thing is it’s hard to get a handle on what’s happening just by watching, even in slow motion. Trying to analyse that I started tracing the arm configuration and spline path of the wrist, and while I was at it also the elbow and shoulder paths, at various intervals of various casts on CAD.
Here is what I have so far. Where possible due to cameras having been on tripods, or other reasons, I was able to make plots of both false casting and delivery casts. I hope you also find this interesting and hope the guys analysed won’t mind being featured.
A bit of explanation first
• The red and blue hopperleg graphs are back and forward positions respectively
• The spline paths are generally: lower one the elbow, middle one shoulder and top one the wrist trace, except in Paul’s case..
• You can see wich part of the spline paths are back or forward by checking which of the blue or red hopperlegs they correlate with
• I included wrist angles also (show rotation timing)
• All the figures containing interrupted line hopperlegs have been taken at exactly regular intervals, with the interrupted positions in between the regular solid line ones. From this some idea of speed at certain stages can be gleaned
Bart de Zwaan – false casting. Small arc and nice smooth figure of eight path. I like this guy’s style! Interesting too that the forward wrist path runs higher than the backcast part, as opposed to basically everyone else!
Bart – delivery. Heavy upward trajectory on the thrust and pronounced jump in shoulder path when he shifts to the front foot. His delivery arc measured 120°
Lasse Karlsson – false casting
Lasse – delivery. High speed between forward hopperleg four and six!
Magnus Uhr – pronounced dip on wrist rotation and then an upward stab
Magnus – delivery. Very late rotation!
Paul Arden – all sorts of things happening, but…
… check out the elegant wrist path on its own
Ronny Landin – false casting. Speed between fw 2 and 4. Paths more aligned than others and with subtle deviations as highlighted here:
Ronny’s delivery stroke
I also traced the rod tip and think the down-up at the end of wrist rotation (circled) is largely responsible for a sustained SLP. P.S. check the loop size!
Steve Rajeff – false casting. From an old file and interesting compared to the others
Steve’s shoot. Down-up circled. Also similar shoulder bounce as with Bart
Technical comments on the down-up hop, and maybe in general?
All the best,
