Paddling pants vs. Wadding pants vs wetsuit?

Anyone have a preference on pants? I rarely beach launch as I'm running a tandem solo. Mostly want to keep dry/warm but thinking about launching from beaches up the coast makes me think wetsuit or wadding pants... the downside to wadding pants is if I end up in the drink could be very difficult to get back on the kayak.

If "wadding pants" =  waders, don't ever do that.  Wetsuit or drysuit only.

If you do some searching on this forum and the Northwest Kayak Anglers Forum, you'll see that there is a long-running dispute between kayakers who think that it's safe to kayak in waders, and kayakers who think that it isn't safe to kayak in waders.  Some kayakers claim that a tight waist belt will keep water out of waders long enough for you to climb back on a sit-on-top kayak, and other kayakers report near-death experiences resulting from kayaking in waders.  My view is that if you end up in the water while wearing waders, even with a tight waist belt, you are likely to end up with wet clothing and a lot of water in the waders, which could prevent you from climbing back on your kayak, and could result in you ending up in the water for a long time, developing hypothermia, and needing to be rescued.  So I recommend that you not kayak in waders.  A drysuit or a wetsuit are the way to go, and in areas which have colder air and water temperatures than California, a drysuit is the way to go.

For times when the air and water temperatures are a bit warm for a full drysuit, but you'd like to keep your feet and butt dry, you can wear a pair of dry pants, if they have a wide and tight waistband which reliably keeps out water, and which won't pop open while you're re-entering your kayak, which for some people appears to be something of a struggle.  I use a pair of Kokatat Tempest dry pants when kayak fishing in the early and late summer in Montana, but I don't trust the Velcro waist closure to stay shut if I have to climb back onto my kayak, so I've added nylon webbing and a Fastex buckle between the Velcro tabs to provide a more secure seal on the waist of the pants.  When kayaking in the fall, winter, and spring in Montana, I wear a full drysuit.

my view is....
y'know, what PMPete said 

I personally use a mysterioso thermal layer, then (I think 5mil) neoprene pants over them.
I sometimes carry a pair of paddling pants if it is going to be cold and raining, as the neoprene can get chilly if you are wet and exposed to wind.

From personal experience when duck hunting  with my brother in a canoe he grabbed a branch and  flipped me out I had on waders a belt a life vest and  it took all of my strength and my brothers to get me back in the canoe in water deeper than my head and I was in my 20s in excellent shape. I was floating  with my nose barely above the water. My reccomendation is that if you dont want to drown dont use waders!
