There's a learning curve, but it's not that much harder than 5 of the same class. I made a post about my setup a while back but I can't seem to find it - you can find a copy here:

It's a bit dated but it should help a bit. I think they key is to get your macros right and get some experience. Start with the easy instances until you have all the key memorized. That way you'll be able to respond to unforeseen things more intuitively. Good luck - it's well worth it :-)
