Opinion on 2015 radar theory VS Ho Nos

[mushamushskier]

I am looking to get a better ski for this summer. I am currently just using a combo 67" ski. I'm 5'6 and 140 pounds, I find the 67" to big so I'm thinking about moving to a 65" 2015 radar theory. I've found a pair of HO basis front binding and rtp for sale locally for a good price. I read that Ho bindings can mount to radar skis?

My other option would be a ( I think 2011) 65" Ho Nos with the basis bindings. The nos is used but in perfect condition but I can find very little info about it online.

Any opinions or recommendations would be great!
