I use a 72.5 head angle and either a 45 or a 43mm rake fork on my personal bikes (roughly the same size as yours). My preference is for longer chain stays, 42.5 cm, and a little more BB drop - 7.5 cm range. My seat tube is also set at 72.5 since I have long femurs. Overall I'm happy with the bike(s) but unfortunately, I don't ride enough these days.
