I've read just about every post related to fly fishing for tuna on this site and first, I just wanted to say thanks for all the info and help to this point. I am looking forward to hooking my first fish. First, I am new to saltwater fly fishing and any serious fly fishing so most of this is all new. I believe I am going to purchase a TFO blue water 10-12 paired with a Ross monument 6lt. Two questions; 1) sounds like the rio outbound line is the ticket. What grain shoulda use? Also, do shorten the head or leave it at the factory length? What's the advantage of cutting it down? 2). Where can purchase the shock and awe flys or similar flys? We do a lot of tuna fishing on our private boat out of northern California so I expect some trial and air. I plan to use the rod to cast to jumpers, the slide and when we have them boiling on bait.
