Due to a recent injury I'm kind of stuck with XC stuff as I no longer have any depth perception and can't really judge the landings anymore. I've got a 140/130mm Trail bike so I'm looking for a light XC style thing.
That sounds like a shitty injury, I'm sorry to hear that. I guess a bike with pretty forgiving handling will suit you best, not something that threatens OTBs by being too racy.
I should add that mine is set up with a 100mm fork with a climb switch that drops it to 80, so if you got a 2018 with a longer fork it's probably quite a different bike.
I haven't ridden the Ridgeline; it is meant to be more compliant. I think the Pro29 gets the stiffness from the twisted tubes.
Have you seen the new Ibis DV9? Not titanium, carbon, but a ripper price ($999 US, haven't seen a local price yet, but you can get it from Jenson for $1500 delivered)
EDIT: they won't ship to Oz, so you'd have to buy local. Worth it for the seven year warranty though.
