I'm semi new to dual boxing. About a year ago I tri boxed a couple sets to the mid 40s before quitting WoW. The expansion and the RAF offer have whetted my appetite again.
In the past my combos were 2 warlocks and a priest, and a paladin, mage and hunter.

However, this is my question: For those who are just starting out and taking advantage of the RAF program, what would the best setup be in terms of choice of class for preparing oneself later on, ie after RAF, if one is interested in boosting other characters and whatnot later? I guess I'm curious what the veterans would consider to be the best classes to take advantage of the triple xp/gift levels to skyrocket them to 60/70 first? The dream team, in essence. From what I gather reading over the forums, any group that includes a paladin would be optimum but is that observation correct? I'm just wanting to get the most bang for my buck while RAF is going on.

Any input would be much appreciated and hopefully you can make some sense of my rambling.
