also known as a Switch cast and Dynamic roll by some, i prefer not to use those terms because of all the confusion they usually create.
simply put, a Jump roll is the other form of roll cast.
instead of dragging the line back on the water to create the D loop, the ‘jump’ part means lifting the line from the water, placing the anchor, creating the D loop in line with the intended front cast direction and going into the forward cast before the D loop crashes on the water.
although hard to disassociate from the Spey cast family, it really isn’t one because this isn’t a change of direction cast. sure, we can deliver the line in a slightly different direction than where the line was lifted but that angle change is very limited.
however, the Jump’s siamese twin of sorts, will be the Single Spey which is based on the same principle but involves a curved sweeping motion and consequent D loop angle change during the ‘Jump/Lift’.
in his dvd set ‘Modern Spey Casting’, Simon Gawesworth highly recommends practicing this cast regularly and to use it to warm-up to start off the day. i couldn’t agree more. it’s not the most useful of actual-fishing casts as it means putting the fly back where it came from and usually causes some commotion on the water’s surface during the lift but ! getting it down right involves good and proper everything: power application, timing, rod tip tracking, smoothness and probably a whole bunch of other elements that’ll come back to me once i’ve published this post…
more than just ‘line-pretty’, this image shows excellent anchor placement involving anchoring only the leader and not the fly line. this provides more than enough ‘stick’ to not blow out the D loop and makes the front cast more efficient and quasi-effortless. superb form indeed.
in this image we’ll also notice that the ‘kiss and go’ principle is far from being a rule or even a necessity as we clearly see the forward cast was started and finished well before the line anchor touched down: a ‘go and kiss’.
’nuff said, here’s some line-candy. enjoy !
