I have an 08 LSV and here's my set-up: 1100 each rear, 490 center (doesn't fill all the way), 750 IBS (sometimes I think the wave is better when the IBS is empty or just slightly filled because there's more pitch), 650 in lead bags placed under seats toward rear on side I want rolled/listed, 2-150 bags on floor towards rear, 325 bag on rear seat. Three reversible pumps and fresh air exhaust. I use a Swell Slim H3X Plus shaper in the rear and sometimes I experiment with another shaper on the same side but toward the middle of boat (some people claim that two shapers are better than one but I'm not convinced). When I first did upgrades in 2016 I used an ACME 1617 prop and then upgraded to an ACME 2937 (per ACME recommendation). Also, check for water under your ski locker (many LSV owners have cut holes in the ski locker to drain water that gets trapped - design flaw).
