Looking for input from anyone fishing jerkbaits from a kayak.
 After reading about all the catches that have been made using jerkbaits, I figure I should start using them too.
 I’d be using a spinning rod probably paired with a Pflueger Supreme 30 spooled with Suffix 832 10lb test.
I would be sitting in my kayak all the time, no standing.
 Also, not looking at spending over a 120$
I’m looking for length and action that has been used by guys.
 Watching videos and guys fishing from boats, it looks like most use a downward motion when working them, not sure that would work for me.

I toss jerks from my canoe, usually from a seated position. I have both a BC and a Spinning rig I toss them with.

The spinning rig is a Trion-30 loaded with 10# Stren Original on a 6'6" M/F Diawa Aird-X .

My motion for working the jerks is mainly to the side with a bit of downward direction - one sweep towards 4-o'clock, the next towards 8-o'clock - rod parallel to the water at the start of the sweep.

What MN Fisher said.  When you're low to the water, you use more of a side sweeping motion, with a little bit of downward direction to it.  I'll usually start with my rod about two feet above the water, and then end with it around six inches above the water.  I probably move the rod from around a 30° angle to the side of the bait to a bit more than a 60° angle.  Whatever feels right.  Play around with it and you'll stumble across something that works for you.  I like shorter rods for this.  I have some older 5'6" pistol grip rods that work well.  Though I've also used 7' split grip rods for it, and they work pretty well too.  But the longer rod handles can get in the way sometimes, and the longer rods can make imparting the action a bit more finicky.  

 

I prefer medium action for just about anything with treble hooks.  With the shorter rods, the medium action blanks tend to load better, and allow me to cast further.  That's assuming that the weight of the lure is appropriately matched to the rod, however.  Plus, the slower action rods help keep those tiny hooks from getting thrown as easily.  And you don't need as much power to set those hooks as you do on larger, single hooks.  

I use a 6'10" Mod/fast but it's a baitcasting rod.  

I let the lip do the work and do quick jerks, probably somewhere between the 2 o'clock to 3 o'clock on one side or the 9 o'clock, 10 o'clock on the other side.   Seems to work for me. 

Thanks guys for the tips, it confirms what I was thinking.
I've gotten back to freshwater fishing after many years of fishing the salt.
I'm thinking I would need a fast tip to work the bait, but as Bankc mentioned medium action with the smaller trebles and lighter line.
Good excuse to stop by my local shop that is a Daiwa dealer.
Thanks once again!
 

I was using a cheap Daiwa spinning rod today that I got from Academy (even cheaper than the Arid X), with a KastKing Sharky II and 8lb Hi-Seas Grand Slam. I think the rod is a 6' 6" M/F and works really well for jerkbaits.
