Take Hannah and Fury on BloodVik and you'll have a Hannah that buffs both the Viks and herself (going up to 4/6 /8 :blast ) I usually go up with Hannah or another more or less tanky model (Ronin works since they can't be charged) first to protect/bait and just charge in afterwards.
I never throw my Viks unsupported into anything unless it's already in a desperate last attempt at countering a bad mistake I've made earlier.
Most people also forget that they are two models instead of one, which counts for lots. After killing only a few models I can just turn them into scheme runners if I feel the need for it, or to swamp a quarter for recon. This is one of the main reasons I usually take them over Von Schill.
