Which size Kuiu Bino Pro Harness is best for 10x42 Swarovski El Range with tracking?

I use the smaller of the two sizes for my 12x50EL. They have zero room for additional length, but I can throw a Samsung S20 in there with them and have extra room.

Not the large .. I have the large and have a 8.5x50 in them and I am down sizing for the x42 I just got
