In choppy water I tend to use the Super Spook and the TackleHouse Feed Popper, and Occasionally the Z Claw. Spook seems to "ride" the chop better than the patchinko, but I think the patchinko is a far more effective lure. When it get to be really pants then the Feed Popper is my first choice.
What kind of luck have you had with the Magnum? I bought one last year and after a few unsuccesful sessions it now rest in the bottom of my lure box.
Is it worth persisting with and in what conditions?
What about the cheap and 'humble' ChugBug in the large size for choppy water.
One of my best all time plugs for 'freshwater' is the Lucky 13 from Heddon,this plug floats very well in a chop and can be worked 'on top' and a few inches below with a few short snaps of the wrist.
Dont know why but I have never tried them in the salt but they should go well in a good chop etc.
Worth a try............:-D
As others, I find the patchinko is definitely best in calmer water, and use a chug bug when it's not right for the patchinko - but that's as much to do with my current selection of just two surface lures in my kit
The classic Yozuri Mag-Popper/slider in the larger size is great in the rough stuff. As is the larger Chug-bug.
If it's windy(in your face) and rough then the Feed Popper 120 gets out there and causes big disturbance.
