Alex, I'm currently flying a Kaos which is an Ultrasport with cheeks and without a turtle deck. I've also lived with the aggravation of a plane with a faired in nose very similar to the US60 only it was a 40 size plane, thus even more confined. It was so slippery I had to take a lap at 1/4 throttle to slow it down for landing!

The large canopy, thick wing and fixed gear of the US60 means you already have a 'dirty' plane from a high speed standpoint. If the plane were mine I'd build it faired per instructions but I have to admit for access, cheeks are nice. Nose gears are notorious maintenance magnets and a faired in nose can make it frustrating. With that said I personally prefer a faired in nose over cheeks (or cowl) on all but the most utilitarian airplanes, both for looks and profile drag. One of the most important streamlining areas is at the nose of the plane near the prop.
