:shock:
First off there's a program called mugenmokey that you can use to theoretically create any build you want.

It's really easy to use.
Next.
Why do you have 24 Str and 25 Dex? :suspect:
I know you need 25 Dex to use the Gold Tracer, but that weapon scales with Dex, meaning it will do a lot less damage than it will do on Dex 40. Using weapons that scale without having stats to back them up will make them do little damage and thus won't do you much good.
24 Str is for Zweihander I guess?
You need only 16 to use that. You will have to use it in both hands, but not only it will do more damage that way, but the moveset is identical, no matter how you hold it.
If you want to use a curved sword like Gold Tracer I would recommend Falchion, or Scimitar, which do similar damage, however they don't have Bleed Aux. They do a horizontal slash, which is great to stop backstab attempts and they also can parry very quickly.
Lastly, on this SL make all your weapons elemental, they will do much more damage than scaling weapons with minimal stats. Picking between Fire and Lightning is entirely up to you, but it's best to have both for PvE purposes. In PvP, it doesn't matter that much which of the you use.
I'd go with something like this.
It seems I have gone ahead of myself.
To answer your original question.
I recomend using Balder Side Sword. It's very fast, has wide horizontal range of attacks, it's very long (if not the longest straight sword) and it's R2 is a powerful poke with incredible range.
Another interesting option can be Barbed Straight Sword. It is a very short straight sword, but it inflicts Bleed Aux, which will complement your Gold Tracer.
You can also use a spear. With your stats a Pike should work well and it has extremely long reach.
I hope this will help you.
