Brogsy I remember that thread. First of all can I suggest you take back the T-curve 400 and get a 200? Hopefully they will let you swap. If you are only using 50 lb line the 400 will not give enough bend to properly fish. It's more suited to 80 lb. I use one on my Saltiga expedition with 80lb. For 50 lb I used a 200 and believe me that little extra rod bend made it a joy to use and still put a lot of hurt on the fish.
Although you have made it hard to snap this rod which is a factor I spose!!
For the Saragosa you could try a T-curve Bluewater spin and once again the size will depend on what size braid. Sounds to me here though the 15-24 kg one will be the one. It is a better allround rod than the GT special.
You could also try the Daiwa monster mesh popper rod for this but I didn't like the feel of it in the shops.
I don't use backing.
I use Black Magic supple trace as my leader as it provides a littel stretch and ties a good knot to braid. I use the Yucatan knot for this. Use 60 lb for teh Tyrnos set up.
I use Gamakatsu Octopus hooks, not circles, either 8/0, 9/0 or even 10/0. I tend to use these for reds.
I also use VMC O'Shaughnesy hooks (T9255PS) in 8/0 or 9/0 size. These are cheaper and good for trout and baiting up with bigger baits like pilchards. Because they are cheaper I use them more as well when the sharks are in plus they are my gang hook rigs for macks. You could go a similar style in Mustad for bottom bashing here too.
For my bootm rigs for reds I tie the leader onto a heavy rolling swivel then 80lb minimum trace (usually 100 lb). I use Black Magic tough trace for this. Jinkai will also be good. I use a paternoster set up. For trout you can do similar but use a bottom hook as well with one of those VMC's on the end.
I think that covers it all?
