Thats not a tuna....
Now THAT's a tuna!
Scott 3 piece 10 wt & Hayden anti reverse reel.
Note it is NOT large arbor - this crap that everyone needs large arbor is just that - crap - large arbor is NICE to have but not ESSENTIAL as many will tell you.
Theres another long tail tuna on fly.

The latest Hayden reels have a few more holes in them these days - the older hand built models still work just as well - I haven't been able to kill mine in more than 10 years of saltwater fly work!
Just get the best gear you can afford at the time - look after if and hope to avoid the usual accidents that beset most fly gear from time to time.
Using it at places where big saltwater fish abide certainly increases your odds.
