So I have been looking for a used Turf Tiger 61" Kohler/Kawai. either motor is fine . The better deals are on the Advantage . I have read where everyone raves over the Velosity. My question Is it worth $1000.00 more for the Velosity. What makes it so much better. I have a 48" advantage now on a tiger cub & it seems to do fine. Any help would be appreciated.
