I have a '17 xt with spokes. Normally I'd go for cast.
Having said that, these ones are unblemished so far. But then I rarely go out on salted roads, partially acf the bike every winter, don't commute, and do a fairly limited mileage. The spokes came with the bike 2nd hand. I quite like cleaning my bike and I like the look of the spokes
Having said that, I've had plenty of spoked wheeled bikes over the years, and each one has had (eventually) a problem or two with spokes (sometimes from being abused! Overloaded, hitting massive potholes abroad etc), wheels needing rebuilding.
All things being equal I'd go cast. They take a lot of beating!
Oh! And the new beaks look good imho
