Repebble is releasing their Pebble Round 2, and I think I want to get it.

But I am not sure how to choose between 14mm vs 20mm straps.

I had an LG smartwatch 3 that had a 20mm strap, and I did not like how clunky the strap was.

But are there upsides/downsides to 14mm vs 20mm? How do you usually choose, and or what is your preference?
