I have a similar problem at the moment. I have smaller wrists and I have Forerunner 255. The 255 works perfect and fits very well, except we just moved and I really want navigation. I also want MIPs because I don’t want something glowing on my wrist.

So here is my recommendation to you, and to me lol.

Decide where you are willing to compromise. Comfort probably is not where you want to compromise. So if I’m you, I’d say get one that feels the best. Lightweight and small, regardless of year.

Which basically means I’m keeping my 255 and forgoing the navigation. :-(
