Again - I'm no expert but here's my take.

The center sheeting is a personal preference. I grew up on cats and the main blocks were always on the back of the boat, and thats where they'll stay for me. People who have more time on dhingys tend to prefer the center sheeting. Whether one is faster in tacking or provides better leverage is a good question. Cleating is again a personal preference. I am currently without a cleat and definately don't miss it on the bouys courses but it is good to have on the distance races or when cruising.

I have the AHPC Flyer and mast rake has never really had the level of impact that it would on other boats i.e. H-20 etc. Its like a Popeel Roticery Oven, set it, and forget it.

Sounds like you've got great taste in boats. All you need locally now is a Capricorn to have the entire AHPC line. F-16, F-18 and A Class. They build great boats don't they?
