yea, a nice little 2 1/2-3' wave is all thats needed for flips n rolls with an AM hull and big power. i used to like them 4,5 or 6 on my beater round nose. that boat is one of our regular favorites, but there are a few that throw a 4-5 footer. the smaller the wake, the harder you have to work. it takes about every drop out of my kart tank to complete one full cycle on our run and i have ran out a few times.
