I've been trying to find two-digit 7 segment display modules to use instead of the single ones... I've tried a couple, and they're just markedly dimmer, so I'm going to go back to individual digits. The incremental cost and trouble just isn't worth it since there is a visible difference in the results.

This also applies to the Pi Zero clock. The GPS clock board version that's going to be the one going forward is going to be 3.0.1 and the Pi clock board will be 1.0.2.

As planned, the 3.0.1 board will have the improved SPI wiring, PPS into ICP2 and the supercap for preserving the almanac across short-term power loss.
