Is the only difference the size?
The bigger screen appeals to me because I don't wear my glasses when I'm running and I really struggle, without my glasses, to read what's on my phone - I currently use that, the Nike-plus app, when I'm running. Does the bigger screen, the 4mm, make a big difference? Can't I have the font on the 47mm Fenix 6 Pro such that it's big and readable?
Does the extra weight make a difference? Is it TOO heavy?
I'd like to get away with the 6 Pro, not go for the 6X (big for every day, all day wear) but I have a feeling that, my eyesight, without glasses, being what it is, I should go for the biggest one?? TIA
