mountaineering Boot - Vasque Radiator

Last year I discover the pleasure of the ice climbing. Now I when to purchase my own stuff and I know that the boot is an important part. I want a versatile boot for mountaineering and ice climbing. I live in Quebec, Canada. I find a boot that I’m very interested by it, because when I try it, the new Vasque Radiator. It was comfortable, light and the boa system look very interesting when you want to close at minus 20C, but I have some difficulties to find information on this boot and the quality of Boa system. Because when I tray in store the steal cable have cut the boot. I don’t if it was defect manufacturing or is like it. I know that its new boot but I would like to know if some one has any comment or information on it. Also, if you know an equivalent boot.
