Sounds like I'll have to spool up one of my reels with some spectra to try it out. I've always used mono & have no real stretch problems with it since most of my yak fishing is done in less than 80 ft, but I can see benefits to the spectra too.
I totally agree with the 20 pound test breakoff thing (although I sometimes use 25 on a heavier rod). 20lb seems to be the best compromise. I used to use soft 17lb and lings would constantly wrap me & snap it. This hasn't happened with the 20lb (I still get wrapped but now the line can take it). I use a 7' Ugly stik tiger or an old custom rod I scored in an antique shop, both with the 20lb on either daiwa or penn reels. Nothing fancy but they work well.
I like to use big scampis & 8' fishtraps for tossing near kelp, and 4-6oz bar jigs with single hooks for deeper jigging. Pretty standard stuff.

I've always wanted to travel the inside passage with just my kayak too. What an adventure. I used to guide kayak tours on Prince William Sound in the 90's and have never forgotten the summers I spent there. My largest salmon from my kayak was probably 18 pounds on 10lb test and a trout rod, a late run silver in September. I recall several blistering runs and tailwalking (for a sec thought maybe it was a tarpon that had taken a wrong turn at Albuquerque). Lots of rain, but some days that would challenge baja too. Huge reds & lings & my buddy Scott caught his first halibut, estimated at 126 pounds (these were off a small powerboat). Prince William Sound Kayak Center has a nice website & the best local knowledge in Whittier AK. Ask for Perry or Lois, they'll help ya.  One of these days I'll get back...
