I've been Kayak fishing for about 6-7 months now. I have a Slayer 10 and sit down 99% off the time. I can relate to the casting while sitting down as it's a new ballgame compared to standing. It's going to take some practice but once you get used to it there really isn't much difference as the rod and the lure pretty much to all the work in the end. I'm getting much better at it with practice. Depending on what combo I'm using and how my thumb is reacting I can pretty much plop my lure wherever I want. When I first started I'd just go into open water and practice casting as it was strange casting while sitting down. To this day I will still do some open water casting while peddling out to where I want to fish. Just remember that your so close to the water that it's possible to dip the tip of the rod and lure into the water when going for the super long casts....Baitcaster and tip/lure dipping can make a nasty backlash scenario.
