In a way, I believe this means that from the craning neck standpoint, the 61 could require less craning if adjusted for with a shorter stem.. but with the SLR01 integrated design, I'm not sure how easy it is to eg. go from the 120mm (61cm bike stock size) stem to a 100mm.

This aside, I don't think a 61cm bike would ever be typically recommended for the OPs size characteristics.
