I'm 6'4" tall and 200 lbs with a 34" inseam. I have problems finding spring and fall tights which are made of the lighter weight fabrics. While at the Great Western Bicycle Rally I bought a set of tights from Giani Kuchurik that fit perfectly.
They have good prices and some really nice stuff like vests that really fit correctly (higher cut arm cutouts then you'd expect are correct) and the correct weight material in their jerseys.
