Replying to Got myself the Cal Carson vishnus but concerned about length

Pretty stoked on the recent purchase but a little worried about the size after reading the numerous threads on NS. I'm 6'0 150 lbs and got the 183's because I ride some arv 184's currently. But after everyone saying that the 189s can help with stability on the wets for someone around my size I'm thinking maybe I should've sized up? Any insight would be appreciated, sorry for another vishnu thread..
