Efficient way to power stacked rows of pistons?
How can I power two vertically stacked rows of pistons, hopefully with a minimal number of repeaters? I can get the bottom row powered with just a line of redstone on the gold blocks behind as shown, but can't figure out how to do something similar for the top row at the same time.

Solution 2:
If you don't care about inverting the signal beforehand, simply use redstone torches behind the upper pistons to power everything:
