Crystal 40 & Vienna as Denny mentioned. Munich works too. Maybe 1/2 lb each, or less, per 5 gallons. Cheers!!!
Just to clarify, you're talking about Caravienne or Caramunich, right? Vienna and Munich malts require mashing, and I'm not sure those were the specialty grains the OP was referring to (I could also be wrong). I think he was referring to more specialty steeping grains.
I've read varying accounts of whether Victory requires a mash or not, and came to the ultimate conclusion that you'd get flavor and color from it, but no fermentables. I'm going to try it out in an upcoming IPA recipe.
As far as other specialty grains, would he benefit from Carapils/Dextrin malts? My understanding is they provide good body and head retention (I'm still new to specialty grains as well, so I speak mostly from book knowledge).
