Light tackle is really only any good for running fish, but for fish that have to be reeled up from the depths then you may find that a light rod and reel won't last the distance, I would stick with the Titus Gold and Kenzaki rod and you will at least stand a chance of landing something bigger.
I remember once when we were wreck fishing for Pollock and when the drift slowed I decided to use a light spinning rod which was almost bent double playing some of the smaller Pollock and it was great fun, then I hooked a big Ling and I thought the rod was going to break so I ended up hand lining it in and it wasn't much fun.
Use the right gear for the right fish and it's fun.
