I'm pricing up a second set of 650b wheels. Currently using WTB KOM i23 with 47mm Horizons.
For gravel ultras and bikepacking/touring where I might run 50mm gravel tyres should I stick with i23 or should I go for wider i25? Or 30g more per rim for the i25 Tough version?

I've heard arguments for using skinnier rims so the tyre sidewall isn't so exposed.
