Any tobacco grown in shade will produce thinner, milder and larger leaves. The plants also grow taller (unless the shade is from nearby trees, which suck the water and nutrients out of the soil as far out as the tips of their branches). The leaf of shade grown plants tends to be more fragile.
CT Shade plants (under shade) grow to 8+ feet, and are unable to support themselves. These require a scaffold and a support wire for each stalk. The scaffold is also used to support the 40% shade cloth, which must cover the top and all four sides of the growing area. Ditto for Dixie Shade.
For a first time grow, I would just go with sun-grown wrapper (which is all I grow). If it's mild, blond wrappers that you want, then sun-grown / air-cured Kelly Burley kilns to lovely, huge, thin, stretchy, slightly nutty-flavored wrappers. The lower leaves of any wrapper variety will kiln to lighter leaf than the higher leaves, with the tips producing very dark wrapper.
