Does the 16 head/tail spin around your wrist? That would be my only concern getting it in the 16. The 15 looks great on you and that’s how I wear mine.So…I bit the bullet prior to increase. I tried on size 15 and 16 (I am juc and clash 15), and although the SA said I was a 15, I opted for the 16 for movement. For ref - 15 is the one closest to my wrist bone. Both 16 on the left.
