As an owner of a 170cc, I would recomend going w/the 190. Don't get me wrong I love my little boat but room and storage space is a big issue. Even with only myself and one fishing buddy it can get cramped after a full day on the water. The reason my family bought the 170 was because of the deal we got on it(dealer leftover), even with the space problem I still would not trade it for any other boat, except maybe a 190bay.
