useless bay/double bluff

Hey fellas,

I am heading to a buddies house on Useless Bay on july 12. I know that there are a few coho there, and that the chinook open on on the 16th.  After looking at the charts, I bet there are cabs there too. Any advice on any of these three?  I was there last year in July and hooked up several coho by just trolling a hoochie right through the bait balls in my buddies boat.  What do I not know about this area?
