Spey Casting Practice - Perry Poke

Here is a video I made to highlight some of the salient points of a Perry Poke (wrap style). In learning the Perry Poke/Wrap, I find it useful to remember the following points:
1) Dump the line in a smooth arc preferably no further than a rod length away from you. Dumping the line too far ahead of you may compromise your D-Loop formation.
2) Pay attention to where you fold the line during the dump as that would be your anchor/pivot point. As a rule of thumb, the joint where the sink tip (or versi-leader) meets the Skagit head would be where you want this fold to occur.
3) The sweep should be should be as smooth as possible transitioning into the forward cast. It is useful to think of the sweep and the forward cast as one continuous stroke with no pause in between. When done right, centrifugal force generated from the sweep will throw the fly line (skagit head) radially outwards, forming a D-Loop that swings round from your front to your rear.
3) Power the forward stroke when the top leg of the D-Loop just about line up with the targeted cast direction. The timing here is crucial to get a good cast. If you wait too long, the D-Loop would have swung round too far and tends to wrap around you in the forward delivery. If you exit the sweep too early, the D-Loop may not form properly and you would not get good loading.
