I have been fishing from my adventure, in reverse with the rudder down, since 2009 and find it a fantastic way to fish lures. I have never tried it with the rudder up as I like the rudder/rod control and too not have to handle a paddle, that I just haven't really given it any thought. Now after reading about it (and if I can get back on the water), I will certainly give it a go on some of my larger/faster deep diving lures.
In reverse I mostly only use one rod, I use one hand for the rod and one for the rudder. Your control lines to the rudder need to be well tuned/tight, as the more play they have the harder it is to keep control. As Roadrunner said, max speed is around 2.5 mph but you really only need 1/2 to 2/3 that speed when working a lure.
You can mix things up a bit, but one way I like, and how I started, was two or three fast pedals as you lift and jig your rod tip high and quickly, then as the kayak slows it's drift, slowly lay the rod forward and let the line lay on the water. Carefully watch your line on the surface for any take, as it often happens when the lure is on the drop or sitting on the bottom. Similar with surface poppers as well, the hit is often when they stop.
As you come to a halt and your lure has hit the bottom, two more kicks and again impart the action, maybe a flick off to the side as well. The Adventure going in reverse, almost turns in its own length as well, well a little exaggerated, but it does turn quite quick and you can change directions very easy, working around weed beds, rock walls or moored boats (and work your lure under them).
Mid water (neutral buoyant), I like to dart them across the sand, from weed bed to weed bed and then let them hover for a second over the weed. And vice verse, hover over the sand and dart for the weed.
Shallow water, I like to put some distance between the kayak and lures if I can. So the fish can settle a little if spooked by the kayak (but with a Yum Yum yellow one, it's not really a problem
The best parts of fishing in reverse, is, the action is no longer behind you, the rise and take, or that first exploding jump are right in front of you. You get to see all of it (well unless you are glancing over your shoulder, to see where you are going. Also worth a mention now, if you are going to tip, that's when it will happen most likely.) You get to work the water for longer, without the cast and retrieve, cast retrieve. You can troll a lure, impart more action and watch the line tension, off the water surface, as you drop your lures. It really is a finesse way to troll lures off the front, or is that back of your kayak (it is still following behind you isn't it)
With the rudder where it is on a PA, I am not sure how the rudder and kayak will react in reverse, turn will certainly be quicker, just not sure how the rudder will handle the water pressure with small manoeuvres. But with any of the other models, it should work fine at slow speeds like the Adventure.
Personally, I love it, and it is well worth the effort learning/trying and I am surprised more people are not trying/doing it, well who I have seen anyway.
