I run pretty much identical to JRW. 750's full, custom locker sac 400-425lbs. Ibs on top of seat and 200lbs pop bags in the bow as far forward as I can get. I ride 24.7mph at 80ft
I also have 150 lbs under my observer rear seat to balance it out as I usually ride with just my wife and daughters. If I get 4 adults in the boat I back off the 750's a bit as well.
For sufring tho I found running my ibs half full to almost nothing gave me the best surf wave. However I ride goofy as does my entire family. I don know guys whe swear keeping the bow sac full helps the surf wave on the regular side. For me tho if I do that it feels like I loose tons of push on the goofy side.
2000 X-Star, 3000lbs ballast, LTR 330, Acme 1235 14.5X14.25prop.
