First timer at IA, Magic heavy party - how will it fare? Options

[jojamie]

Hi all

I stumbled on this mod much by accident and it has thrown me back into adventuring through Baldur's Gate for the first time in a couple of years.
So thanks Sikret for all your hard work, and continued work

So, on to my question. I am a sucker for magic, and seem to always lean to a magic heavy party. What I would like to know is will it be fine to run a magic heavy party in IA or do I need more fighter types.

Here is my proposed party:
F/M Multi - always played dual, and can't drag myself away from being a magic user
R/C - Jaheira
Auramaster or Blade - Cernd or Haer'Dalis
Stalker - Valygar
T->Mage - Nalia
Sorcerer - Imoen

Out of the above, I have only ever take along Jaheria and Imoen. I won't leave Imoen out of my party - shes my sister!
I also wanted to try new NPCs (even if I tweaked them) as I want to hear the banter.

My standard party of old was F->M, Imoen, Jaheira, Minsc, Keldorn and Anomen.
So time for a change.

So, will my party be fine, or will I find myself in a constant reload or throwing the towel in and restarting with a new party??

I am open to suggestion, but don't want to hear spoilers - I am looking forward to the challenge.

One other question - would a triple class protagonist work? I am undecided but lean to the double-class.

Also, what is the Vagrant like to play - would he be better than using a F/M, or would I replace Valygar with him??

Sorry for all the questions
