Just picked up a new pair of surface green lifes that are 100mm at the waist. Also grab a pair of used Rossi axial2's from a NS'er and the brakes are 120mm. Actually physically having the skis now the amount of space between the edge and the brakes is pretty apparent. Should i buy a new pair of brakes and replace the 120's? I think the next smallest size that Rossi has are 100mm so my question is will these actually fit a 100mm waist ski? Thanks +K for help
