Which one planes earlier: C161-F155-IS144?
Hopefully somebody off the Starboard team will answer your question.
A few years ago my husband owned a Carve 161 which we didn't like because of it being too "easy". We preferred at the time the Carve 131 which we owned too.
Now we are looking for a replacement of the Freeformula 158 2004 and the S-Type 137 2007.
The Futura 155 could be an option but we fear the same lack of sharpness like we experienced the Carve 161 at the time.
