See any holes in my party? Options

[Hideous the W...]

I have the hardest time finishing BG/TOB! I always get tired of my parties and want to start anew. The farthest I've made it in IA is to the Twisted Rune. This will be my 4th run through v5: The 1st I had tons of reloads, was frustrated as heck but made it to the aforementioned TRune. The 2nd I did better, a lot less reloading but up to 8 or 10 on some of the harder battles. I think my last fight on that one was with the Chromatic Demon. Then for my 3rd try I tried out Sikret's party in his journal and I have to say I only had 3 reloads going into the Planar Sphere(not counting the dozen with Faldorn ) but I'm already sick of Anomen and Nalia. I just don't like using what is popular at the moment, and it seems Anomen, a Berserker, a Vagrant, a Sorceror and Nalia are mainstays in quite a few parties.

On this attempt at finally going all the way I'm going to take:

Protagonist - Fighter/Druid
custom - Wizard Slayer ?Dwarf?
Edwin
Viconia
Haer D'alis
Korgan

I think I'm getting the hang of things but this party will be a little tougher than Sorceror/Vagrant etc. I think. What I need help deciding is if a Dwarf is okay for my Wizard Slayer and what weapons he should take. Also money may be a problem. I'm not a heavy role player so I'm not sure about what I'll do about Rep. Should I install the low rep discount, screw rep and just power game, or hover around average and just pay a ton of money for things.

So if you were to be given this party what would you strive to obtain and what would you watch out for.

Thanks
