you're right I missed that the 735 has a 0.02" bigger screen! Still I think the 240x240 display (vs. 215x180 I think) will make quite a difference.

> I think that 88g (fenix 5) vs 44g (735xt) is anything worthwhile mentioning
So basically you could wear 2 735s and still be no lighter than one Fenix 5...
Heh, sure... but just saying that 44g makes no or at most neglect-able difference performance wise so the only thing would be 'comfort-ability' I guess (not sure if that's even a word) but when you have to put it on tightly I don't think that's a point either.
Anyway, it's all personal just as deciding if it's worth the money is. I regularly buy a new phone, some will call me crazy but for me it's worth it and I'm lucky enough to have the money for it. Same with this watch, if you have the money and decide you want to do it and don't regret it afterwards it's all worth it right? :)
