We boated a (74inch) 200 pound Swordfish with a Titus 50w as well as quite a few other Swordfish and the reels work fine. I have one and a friend of mine has a couple, I like them. They are
light and with the braided line you have capacity. I also have a Titus Gold 50w II, it is new and I haven't caught anything with it yet. It is a cheap ($$) reel seems to be built well, just checking it out see what happens.
I have 2 TLD 50w 2 speeds, like them. We boated a 215 pounder on the same reel the night before Christmas. I also have (2) 9/0, (1) 6/0 and a
international 50. they all have caught a chit load of fish from Tuna/Marlin/Mako thru Swords and did the job fine, never been spooled yet. I am going to be selling off some of my gear and switch over to Tiagra 50w's and 80w's not because my gear is no good. I think at this point I want to have gear that is all the same and not a hodgepodge.
If you are starting off from scratch, listen to what Cary said and try and buy good gear from the get go, so you don't lose a good fish because your gear was inadequate. Always be prepared for the unexpected, those guys got one heck of a huge Mako a few weeks back, they had the right gear. You always want to have the right tools to get the job done.
