oh, definitely. i was more comparing the construction of the binding than the din range.
god knows i dont ride an 18 lol
IMO if you are asking on NS then there is NO WAY you should be buying an 18 din high performance binding.
although i do like the more bomber toe of the 155-185 VS the former 120 toe. (having both mounted on different skis)
not to mention if you buy at the right time you can get the 140s super super cheap. my shop was closing them out for 180.
