I can't speak for that particular Reba fork, but the 100mm QR I had briefly on my RIP with a 180mm rotor, what with weighing 240 wet, a 2008 model, was a flexy noodle under my weight and downright dangerous. It had a strong tendency to chatter while flexing, and pulling unbelievably hard to the left under hard braking.
I ended up going with a Manitou 120 x 20mm throughaxle. Much, much better in the chattering and flex department.
