The 240 is the way to go. I was able to ride behind the 230 w/ 330 and you can tell the slight difference in the holeshot both driving and riding. Like Mitch said from M&M were i bought my beauty, it all depends on the elevation your running at and i think the 6.2 240 that i purchased is the best all around for the elevatons that i ride. The Sideswipe is a must if you plan on surfing, ya it's a little loud but there is a cure for that. 4-6" Skylon tower tubes and a 4 channel amp. Crank It!
