Hmm I'd not taken the time to browse the latest VRS spec, but man that's good. I imagine most of the whining would be toward the Guide RE's but I've happily run them on 2 bikes, so a maybe spend the cash on a new FF helmet instead, for more gravity orientated riding this will encourage?
Personally I'd dump the 12 speed and go 10/11 for more durability but that would make the spec queens squeal in pain & maybe stiff you if you do have further warranty issues
