I would agree on 1/2" being a good alternative. The 1/2" would only require a connector at both ends, eliminating 4 connectors that would be used on the jumpers when using 7/8" line. After eliminating the loss (and potential problems) of the 4 connectors, 1/2" would come close to matching the 7/8" in line loss.
