Being a sailor often means that you love to make things work, and you buy things to make things work, and you invent things to make other things work. Being a guy means also that more stuff is good and too much stuff is better. It's a guy thing unh unh unh yeah.
But I really have to question whether these fine trim arrangements are practical and useful from out on the wing or is it just one more thing to try and attend to? I think that attention to your course, other boats (tactics), the wind, your hull trim (moving weight forward or aft) and controlling the main to the best of your ability is enough to get you ahead. In other words, just doing all the things it takes to sail well will yield more results than all this fine trim - especially when you are out on the wing in a hard blow (that's the only time you are out on the wing come to think of it)
Not to say if you want to spend the money and do all the stuff to not do it. Heck yeah!
To paraphrase Ricardo Montalban: It is better to look good than it is to sail good- and we look marvelous!!
