There aren't really any descents in Alberta that require them, I've been to California and was a little worried about the rims heating up but found at worst they were warm.
I'm starting to think these stories of tubes bursting from rim heat are either due to poor braking technique or marketing from disc brake companies.
As far as rain, how many of us really ride in the rain, maybe 2 to 3 times a year for me.
As far as weight, my EE brakes weigh 150grams for the set, hard pressed to make that up at a reasonable cost. Cost of a groupset and rims you may as well buy a new bike.
