Slicer is a very valid option for hunter. 80 hit SJS is pointless when Ultima Reaper has more range and ATA, I'd only suggest it to people who have a bit more gear. Anyway, Arrest is really only helpful in Ep4. Charge Vulcans are also good when things are frozen if you don't have Psycho Ravens. Jizai is still pretty powerful, so it can't hurt to carry those, although 10 year blades with special are better. Master Sword, Crimson Sword, Sil Dragon Slayer, and TJS are all decent dps options for sword that aren't too expensive. although for CCA I don't find myself using a sword too much. You mainly want good mechs and a high hit hell weapon. Pyscho Ravens are what you obviously want but they are a bit expensive with stats. Hell Raygun, Hell Suppressed Gun, Hell Water Gun, and Asteron Striker are all decent choices but I'd personal go with Asteron Striker because it's cheaper and has more ATA than the other choices IIRC, plus the auto-aim is pretty nice for Gees and stuff you might find in CCA.
