Yeah I spent like a day on making the pre-struct(its still a struct set up I was just hitting a learning curve), while the post struct took me less then an hour to set up(after I understood structs more). Now I’m doing option 3, wish me luck LOL. However I would prefer a Buoyancy system that gives me more control for individual test points and that does not punish me for using more then 4. Handkors Buoyancy has that kind of effect and if I add one to try and balance a particular area it throws everything out of whack, no pun intended, its just the math is doing a force adjustment based on the total number of test points rather then calculating independently.
