Some of your stuff sounds very similar to mine as I use the Airflo 35' and 45' heads on my Daiwa 9 wt. and 11 wt. I also have the 300 and 400 Big Boys. Though I haven't been able to get down to the salt in the last couple of years, I hope to be able to use these rods for stripers one of these years.
For your cutts, an acquaintance of mine uses a Scott 11'9" Arc 6 wt. for bone fishing in Florida. He loves the rod and swears by it. It sounds just about right for what you'd be doing.
