D&D 3E/3.5 Castle Whiterock 3.5 or Pathfinder?

[GameOgre]

I was challenged to run the entire Castle Whiterock for my group. We have all the 3.5 books as well as all the Pathfinder core books and a few others.

I am not that experienced with 3.5 or Pathfinder but I do have a lot of time Dming other editions under my belt. I am however rather lazy when it comes to spending a whole lot of time prepping the game. A hour or two per game session is ok,beyond that im fudging things.

I do not have to have everything balanced or by the book but I would like to give the PC's a run for there money.

If I used Pathfinder for our games is it going to cause major issues? I realize Pathfinder characters are more powerful but this group runs old school style races and class's and really they are known for getting in over there heads so maybe it will work out? Im not against throwing a extra monster or three at them to make them work for there money from time to time.

I could just use 3.5 but dang it some of my Pathfinder books have never been opened!

Let me know what you guys think and if it's not too much a pain what you think I should do to make things balanced as far as beefing up the monsters go.

Thanks for your Help!

My main group is currently using Pathfinder to do a joint Castle Whiterock/Rappan Atthuk game. So far I have yet to have any problems converting as we play.

You could easily run Castle Whiterock under Pathfinder rules, pretty much converting on the fly as needed. Just use the bestiary critters in place of the normal 3.5 critters where appropriate. For named and built up critters included in the module, run them pretty much as is knowing you might need to come up with the CMB/CMD on the fly.

I say go for it - Castle Whiterock with Pathfinder rules would be fun!
