Finding voltage at points Y and Z in a resistor circuit

[Busybee12]

For the circuit shown below, determine
i) The voltage (V) at points Y and Z.
ii) The current through each resistor.

For (i) do I have to split into series and parallel?

There are at least three approaches to solving this problem:

1. Use KVL on the four mesh currents for each loop.
2. Use KCL on each of the four nodes.
3. Use the equivalent resistance method, and recursively work your way to the locations in which you're interested.

Which approach sounds the best to you?
