first run of IA in EE, questions about party Options

[rbeverjr]

I think I will run a party of 6 as recommended with a (1) vagrant protagonist, (2) sorcerer, (3) thief-wizard dual (Nalia) or wizard, (4) kensai (using 2H weapons), and (5) Cernd, auramaster. My question is about the sixth slot. I am thinking either a berserker 13-cleric dual or a riskbreaker. Which do you advise and why?
Second question. If I recall, Ease-of-Use has a component to get rid of locks and traps. I am thinking about using that. Would that be OK?

Weimar did not like my Steam BG2 EE install. I could not get it to work. So, I used the G3 Tweak Anthology. I made a very minimalistic install. It looks like IA has some options in the install that I never saw before! (I've been around since IA3.) Does anyone know if this install will cause problems?

I've decided to use a risk breaker in the sixth slot. I'll be doing a lot of babysitting of my melee guys at the start. From past experience, I know the vagrant can tank somewhat with the right equipment (ToB); the risk breaker can take care of himself for the most part at high level (ToB); and the kensai will try to be on the second rank with the 2H weapon. The risk breaker is the swingman too. He'll sit out while I do NPC quests.
