Vs an odd front you are basing both the 4 tech and edge rusher as your Qb is reading the will. Base tight is a great front as a 4i really messes with traditional blocking techniques. Hard to get a good double unless you cheat your splits down.
One small note: when running inside zone with a pass tagged to it most teams will still run block on the backside. The term is usually called lock. Locking the tackle or the TE on the edge player to ensure no free rusher.
