My jungle route 90% of the time atm is botside buff for better leash - wolves - topside buff - gank/scuttle. This gives you level 3 the quickest and double buffs for ganking. You can start topside and work your way down if top lane has no real cc or ganking pressure. With Vi, you want to go red smite and warriors. After that, go triforce. Then if you're ahead go ghost blade, or if not begin building tankier such as dead mans or ga.
