Hey Wade
Can't help with launch spots out of Campbell but I used to fish out of Lund quite a bit. Stored the trailer and truck at the hotel and have a shred of a clue about some fishing spots (just a shred; other guys will chime in, I'm sure)
Springs--- Hurtado Pt (just south of Lund) also called the "Iron Mine" --- huge catcher's mitt for bait along the rock bluff---some big springs come out of there---quick hit spot from Savary
Also, Sarah Point (entrance to Desolation Sound)--also a quick hitter from either Lund or Savary---I had good success there for springs, especially on a PM flood
There's also Sutil Channel (west of Cortes) --lots of "character" spring spots, especially near Penn Islands
there's also a sexy reef south of Savary (between Savary and Powell R.) I forgot what the reef is called but it can be productive---very obvious on a chart---watch your depth on a low tide!
I caught piles of lings everywhere (Thulin Passage and Bliss Landing stand out)
If you want to burn gas, the guides go way into Toba Inlet for springs
I heard a lot of Lund guys talk about the "good old days" ---some guys even told me I was wasting my time; the springs were long gone. I took that with a big grain of salt; caught enough springs and lings to be happy.
You'll have a blast---it's gorgeous country. If you have kids, go into Tenedos Bay inside Desolation Sound and hike up to Unwin Lake and take them swimming, or Roscoe Bay (nice lake there too)
have a good trip!
