Hello Walt,
Your fishing requirements are very similar to mine, we both being of similar age, fishing style, outlook etc.
The best reel that you could go for would probably be a Saltist 30H. A very close 2nd would be the Torium 14. The Torium 14 is a lovely little reel with tremendous cranking power and drag for it's size. It is the same reel as the Trinidad 14, except that the side-plates are made from the normal Torium crappy materials and not the solid frame like the Trinidad has. All the working parts are further the same.
The advantage of the Saltist is more line capacity ~ basically the same as the SLX-30 that you now have. The Torium 14 would give you about 100mt less, but has a stronger drag. I have not upgraded the drag washers on my reels yet and they are still the originals. We tested the drag on both these reels with an electronic scale and the Torium has just over 3 pounds better drag (no matter what the Saltist manual says). Both reels have very similar torque (cranking power). The Torium irritates at first, because for some reason unknown to me, the handle is centred on the reel. All other reels that I own have the handles set off-centre. Centred means very small, tight turns of the handle when reeling in and this feels strange at first and is quite tiring until you have gotten used to it.
So as far as the reels go I would suggest the following:
For a 4mt or shorter rod = Torium 14
For a 4mt and longer rod = Saltist 30H
Do not get a 400/1 if you plan to use this rod and reel at Strandfontein/Macassar. Deon has a 400/1 and he only uses it where he can fish with a 3- and 4oz sinker and never against the wind. When you have to cast against the wind from those beaches, you will mostly have to use a 5oz grapnel to get distance and prevent overwinds. The 400/1 is not made to cast a 5oz sinker and is to 'slap' to get a reasonable distance with it against the wind. Get a stroke 2 right from the start and you will be able to cast between a 3- and 6oz depending on the circumstances, a 4 oz being the best for this rod (for me anyway, most other people I know only use 5oz on there 400/2).
I will see you this weekend and we will have ourselves some fishies.
